1N5644 Description

Short technical summary and product information.

The Microchip Technology 1N5644 is a unidirectional Zener TVS diode from the 1N5629 thru 1N5665 series, designed to protect sensitive electronics from voltage transients. It offers a peak pulse power rating of 1500W (10/1000µs) and a working voltage of 43.5V. The device responds to transient events in less than 100 picoseconds, clamping overvoltages and safeguarding downstream components.

 

This TVS diode is housed in a hermetic-sealed DO-13 metal package (also designated DO-202AA) intended for through-hole mounting. It operates over a wide temperature range of -65°C to 175°C, suitable for demanding industrial and avionics environments. The part is rated for a peak pulse current of 34.5A and does not include power line protection; it is optimized for general-purpose transient suppression applications.
