1N5645A Description

Short technical summary and product information.

The 1N5645A is a unidirectional transient voltage suppressor (TVS) diode from Microchip Technology, designed to protect sensitive electronics from voltage transients. It features a reverse standoff voltage of 28.2 V and a clamping voltage of 45.7 V, making it suitable for 28 V nominal systems.

 

This device can handle 1500 W of peak pulse power (10/1000 µs waveform) and a peak pulse current of 33 A. Its response time is less than 100 ps, providing virtually instantaneous clamping for protection against ESD, EFT, and inductive switching transients.

 

The 1N5645A is housed in a hermetically sealed DO-13 (DO-202AA) metal package with axial leads for through-hole mounting. It operates over a junction temperature range of -65°C to 175°C and is designed for general purpose applications.
