The Microchip 1N5642A is a unidirectional transient voltage suppressor (TVS) diode designed to protect sensitive electronics from voltage transients. It features a reverse standoff voltage of 20.5V and a clamping voltage of 33.2V at a peak pulse current of 45A. With a peak pulse power rating of 1500W (10/1000µs) and a response time of less than 100 picoseconds, it provides fast and effective clamping of transient events.
This device is housed in a hermetically sealed DO-13 (DO-202AA) metal package suitable for through-hole mounting. It operates over a wide temperature range of -65°C to 175°C, making it suitable for demanding environments. Typical applications include protection against inductive switching transients, induced RF effects, and secondary lightning surges per IEC61000-4-5.
The 1N5642A is part of the JEDEC-registered 1N5629-1N5665A series and is also available in military qualified versions (JAN, JANTX, JANTXV). Its Zener-based design ensures reliable unidirectional clamping with no power line protection feature.
The reverse standoff voltage is 20.5V.
The clamping voltage is 33.2V at a peak pulse current of 45A.
The peak pulse current is 45A.
The peak pulse power is 1500W (1.5kW) under 10/1000µs conditions.
It clamps transients in less than 100 picoseconds.
It is available in a DO-13 (DO-202AA) through-hole package.
The operating temperature range is -65°C to 175°C (junction).
