## Summary description

Through-hole rectifier diode in DO-41 package rated for 400 V reverse voltage and 1 A forward current. Intended for general-purpose power rectification, protection circuits and low-current power supplies. THT design allows soldering to PCB or use with wire leads. Compact DO-41 body ensures easy integration into repair, prototyping and small electronics assemblies.

## Long description

Diode THT 400V 1A DO41 is a through-hole rectifier diode designed for general-purpose power rectification and protection tasks. The device supports up to 400 V reverse voltage and 1 A continuous forward current in a compact DO-41 package. Its THT form factor with radial leads is suitable for soldering to printed circuit boards, wire-wrapping or use in repair and prototyping where a robust, easily replaceable rectifier is required.
Advantages
The DO-41 packaged diode offers reliable reverse-voltage protection and steady forward conduction for low-current power supplies and signal rectification. Its through-hole leads facilitate manual soldering and mechanical stability on PCBs. The component’s simple polarity marking and compact cylindrical body make identification and replacement straightforward during maintenance or assembly. Thermal behavior and current rating are appropriate for moderate dissipation in small assemblies when used with basic heat sinking or ambient cooling.
Suitable for
 General-purpose power rectification in low-current power supplies
 Protection circuits against reverse voltage and polarity errors
 Repair and refurbishment of consumer electronics and small appliances
 Prototyping and hobby electronics requiring through-hole components
Key specifications
 Maximum reverse voltage: 400 V
 Maximum continuous forward current: 1 A
 Package type: DO-41 (through-hole, axial leads)
 Typical mounting method: solder to PCB or secure with leads for manual wiring
 Intended application: rectification and over-voltage protection in low-current circuits
How to use
Identify the diode polarity marking on the DO-41 body and match it with the circuit’s polarity. For PCB installation, insert axial leads through the board holes, orient the cathode and anode correctly, and solder using an appropriate iron temperature and flux to ensure a clean joint. Trim excess lead length after soldering if necessary. For wire connections, bend leads as required and solder to wires or terminals, ensuring secure mechanical support to avoid strain on the solder joints. Observe the diode’s voltage and current limits to prevent overheating or failure.
Usage recommendations
Use the diode within its 400 V reverse and 1 A forward ratings; provide adequate cooling or a heatsink if used near the maximum current or in elevated ambient temperatures. Avoid exceeding peak surge currents and verify polarity before powering the circuit. For long-term reliability in assemblies with higher dissipation, consider mounting the diode with a small insulating spacer or adding airflow near the component.
