1N5408 Description

Short technical summary and product information.

The 1N5408 is a standard recovery rectifier diode from Diotec Semiconductor, designed for general purpose rectification applications. It features a maximum repetitive reverse voltage of 1000V and an average rectified forward current of 3A, making it suitable for high-voltage power supply circuits. The forward voltage drop is typically 1.2V at 3A, with a reverse recovery time of 1.5 µs, indicating standard switching performance.

 

The diode is housed in a through-hole DO-204AC (DO-15) axial package, providing robust mechanical mounting for PCB assembly. It operates over a junction temperature range of -50°C to 175°C, ensuring reliability in demanding thermal environments. The component is RoHS3 compliant (low confidence), and the MSL rating is 1 (unlimited).

 

Typical applications include AC-to-DC conversion, freewheeling diodes, and polarity protection in power supplies and industrial equipment. The standard recovery characteristics are suitable for line-frequency rectification where fast switching is not required.
