1N5651A Description

Short technical summary and product information.

The 1N5651A is a unidirectional Zener-based transient voltage suppressor (TVS) diode from Microchip Technology. It is designed for protecting sensitive electronics from voltage transients caused by inductive switching, RF effects, and secondary lightning surges. With a peak pulse power rating of 1500W at a 10/1000µs waveform, it clamps transients in less than 100 picoseconds to a maximum clamping voltage of 77V.

 

This device features a working voltage (V_RWM) of 47.8V and can handle a peak pulse current of 19.5A. It is housed in a hermetically sealed DO-13 metal package with axial through-hole mounting, providing robust mechanical and environmental protection. The 1N5651A is part of a broader series that includes military qualified versions (JAN, JANTX, JANTXV) for applications requiring higher reliability.

 

Typical applications include general purpose transient suppression, protection of avionics and electrical systems, and compliance with IEC61000-4-5 surge, IEC61000-4-2 ESD, and IEC61000-4-4 EFT standards. The device does not include power line protection and is intended for unidirectional operation.
