Product information

Description

Through-hole rectifier diode rated for 400 V reverse voltage and 3 A forward current, designed for DC rectification in a wide range of electronic circuits. The THT package with axial or radial leads (PCB through-hole mounting) provides straightforward installation on printed circuit boards and reliable conduction for moderate-power applications such as power supplies, chargers and motor drive circuits.

Advantages

This 400V 3A rectifier diode offers stable reverse voltage protection and consistent forward conduction for DC rectification. The through-hole (THT) format simplifies soldering and mechanical mounting on PCBs, improving durability in environments with mechanical stress or frequent handling. Low-profile thermal characteristics and proven semiconductor construction deliver dependable switching performance for moderate-power designs without complex thermal management.

Подходит для

  • Силовые источники питания и блоки выпрямления
  • Зарядные устройства для аккумуляторов и портативной электроники
  • Контроллеры и драйверы двигателей постоянного тока
  • Схемы выпрямления в промышленных и бытовых приборах
  • Ремонт и прототипирование плат с THT-компонентами

Key specifications

  • Maximum reverse voltage: 400 V
  • Maximum forward current: 3 A (continuous, subject to thermal limits)
  • Package type: through-hole (THT) with PCB leads
  • Typical application: DC rectification and switching in moderate-power circuits
  • Mounting: PCB through-hole soldering

How to use

Place the diode on the PCB so the cathode and anode align with the circuit polarity; observe proper orientation to ensure correct DC rectification. Solder the leads to the board using recommended soldering temperatures for through-hole components, and allow adequate cooling time to avoid thermal stress. Consult the circuit design for appropriate heat dissipation measures: for continuous currents near 3 A, ensure the PCB copper area and any available heatsinking are sufficient to maintain safe junction temperatures.

Usage recommendations

Verify polarity before powering the circuit and avoid exceeding the specified reverse voltage and continuous forward current. For pulsed or peak currents, confirm the diode’s surge current capability in the circuit datasheet. When operating near maximum ratings, provide additional PCB copper or external heat-sinking and follow standard ESD handling and soldering precautions.

Диод выпрямительный для монтажa в отверстие плат (THT), рассчитан на обратное напряжение 400 В и прямой ток до 3 А. Предназначен для выпрямления постоянного тока в источниках питания, зарядных устройствах, драйверах двигателей и других электронных схемах средней мощности. Корпус THT с выводами для пайки обеспечивает простую установку и прочное механическое крепление на печатной плате.

Преимущества

Диод обеспечивает устойчивую защиту при обратном смещении и стабильную проводимость в прямом направлении при выпрямлении. Формат through-hole упрощает пайку и повышает механическую надежность в условиях вибраций или механических воздействий. Конструктивные и тепловые характеристики пригодны для эксплуатации в схемах средней мощности без необходимости сложного теплоотвода.

Подходит для

  • Силовые выпрямители и блоки питания
  • Зарядные устройства и зарядные модули
  • Приводы и контроллеры двигателей постоянного тока
  • Ремонт и прототипирование электронных плат с THT-компонентами
  • Промышленные и бытовые схемы выпрямления

Ключевые характеристики

  • Максимальное обратное напряжение: 400 В
  • Максимальный прямой ток: 3 А (непрерывный, с учётом тепловых ограничений)
  • Тип корпуса: монтаж в отверстие (THT) с выводами для платы
  • Применение: выпрямление и переключение в схемах средней мощности
  • Монтаж: пайка в отверстие на печатной плате

Как использовать

Установите диод на плату, соблюдая полярность: анод и катод должны соответствовать схеме. Паяйте выводы в соответствии с рекомендованными температурами для THT-компонентов, избегая перегрева. Обеспечьте достаточную площадь медной дорожки и, при необходимости, радиаторы или тепловые переходники для отвода тепла при продолжительных токах до 3 А.

Рекомендации по использованию

Перед подачей питания убедитесь в правильной полярности и не превышайте указанные значения обратного напряжения и постоянного тока. При кратковременных выбросах тока уточните импульсные характеристики компонента. Применяйте стандартные меры по защите от ЭСР и рекомендации по пайке для повышенной надёжности.

Caursitiena (THT) dioda, paredzēta līdzstrāvas taisnošanai, ar maksimālo reversālo spriegumu 400 V un maksimālo tiešo strāvu 3 A. Konstrukcija ar vadiem montēšanai drukātajā shēmā nodrošina vienkāršu uzstādīšanu un stabilu darbību vidējas jaudas lietojumos, piemēram, barošanas blokos, lādētājos un motoru vadības shēmās.

Priekšrocības

400V 3A taisnotāja dioda nodrošina drošu aizsardzību pret reverso spriegumu un stabilu tiešo vadītspēju taisnošanas režīmā. THT korpuss atvieglo lodēšanu un nodrošina mehānisku noturību uz plates, kas ir būtiski remontdarbiem un prototipēšanai. Tepeliskās īpašības un konstrukcija ļauj izmantot komponentu vidējas jaudas shēmās bez sarežģīta dzesēšanas risinājuma.

Piemērots lietošanai

  • Barošanas avoti un taisnošanas bloki
  • Akumulatoru lādētāji un barošanas ierīces
  • Moto vadības vienības un DC motora draiveri
  • Plates remonts un prototipēšana ar THT komponentiem
  • Mājsaimniecības un industriālas taisnošanas shēmas

Galvenās specifikācijas

  • Maksimālais reversais spriegums: 400 V
  • Maksimālā tiešā strāva: 3 A (nepārtraukta, atkarībā no siltuma režīma)
  • Korpusa tips: montāža caur caurumu (THT) ar vadiem
  • Parocība: līdzstrāvas taisnošana un pārslēgšana vidējas jaudas ķēdēs
  • Montāža: lodēšana uz PCB caur caurumiem

Kā lietot

Novietojiet diodu uz plates tā, lai anods un katods atbilst jūsu shēmai; pareiza polaritāte ir nepieciešama taisnošanai. Lodējiet kontaktus atbilstošā temperatūrā un ļaujiet detaļai atdzist pirms pārslēgšanas strāvas. Ja strāva tuvinās 3 A, nodrošiniet papildu vara laukumu uz plates vai siltuma novadīšanas risinājumu, lai uzturētu drošu krustotņu (junction) temperatūru.

Lietošanas ieteikumi

Pārliecinieties par pareizu polaritāti pirms barošanas ieslēgšanas un nepakļaujiet diodu sprieguma vai strāvas pārsniegumiem. Ja strāvas impulsi var pārsniegt nominālo, pārbaudiet komponenta īslaicīgās strāvas īpašības. Ievērojiet ESD aizsardzību un ieteikumus par lodēšanu, lai nodrošinātu ilgāku darbību.
