NPN Transistor EB143588097 45V 0.1A

NPN transistor EB143588097 45V 0.1A is a small-signal bipolar junction transistor designed for low-current switching and amplification. With a maximum collector–emitter voltage of 45 V and a collector current up to 0.1 A, this component is suitable for signal-level tasks in electronic circuits, prototype boards, repairs and hobby projects where compact, reliable switching or amplification is required.

Advantages

The transistor offers a balance of voltage rating and low-current capability that makes it useful for signal processing and low-power switching. Its compact package and standard pinout simplify installation on through‑hole or breadboard layouts. The device features thermal and electrical characteristics appropriate for small-signal stages without requiring complex supporting circuitry.

• Низковольтные сигналовые усилители
• Малотоковое коммутационное управление
• Прототипирование на макетных платах
• Ремонт электроники и замена стандартных маломощных транзисторов

Key specifications

• Type: NPN bipolar junction transistor
• Maximum collector–emitter voltage (Vce): 45 V
• Maximum collector current (Ic): 0.1 A
• Intended use: small-signal switching and amplification
• Package: compact through‑hole or SMD variant depending on assembly (check physical package before installation)

How to use

Install the transistor according to the circuit schematic, observing correct pin orientation for emitter, base and collector. Use appropriate base resistors to set base current and avoid exceeding the maximum collector current of 0.1 A. Ensure the device operates within the 45 V collector–emitter limit and provide adequate heat dissipation if the transistor is used near its maximum ratings. When replacing an existing transistor, verify pinout and package compatibility before soldering.

Usage recommendations

For reliable operation, limit continuous currents well below the maximum rating when possible, use a base resistor sized to achieve the desired collector current without overdriving the base, and include a flyback diode when switching inductive loads to protect the transistor from voltage spikes.
