The 1N5643A is a unidirectional transient voltage suppressor (TVS) diode manufactured by Solid State Devices Inc (SSDI). It is rated for 1500W peak pulse power at 10/1000µs waveform, with a working voltage (V_RWM) of 37.5V and a peak pulse current capability of 40A. This device is designed for general-purpose transient overvoltage protection across a wide range of electronic circuits.
The 1N5643A features a single unidirectional channel and does not include power line protection. It operates over a temperature range of -65°C to 175°C, making it suitable for harsh environments. The diode's response is fast, clamping transients within picoseconds.
Packaged in a hermetic sealed DO-13 (DO-202AA) metal case, the 1N5643A supports through-hole mounting with axial leads. This package provides robust mechanical and environmental protection, ideal for high-reliability applications. The axial lead style facilitates easy insertion into PCBs or point-to-point wiring.
