That 22V standoff means it sits across a 22V nominal rail or signal pair and stays out of the way until a transient exceeds 24.4V breakdown — then it clamps at 35.5V max to shunt the surge. With a single bidirectional channel, one device protects a differential pair or a signal line referenced to ground, saving board space versus two unidirectional diodes. ## Peak pulse power and clamping — what 500W means The 500W peak pulse power rating is tested with a 10/1000 µs exponential waveform, a standard surge shape for telecom and industrial transient testing. At the 22V standoff level, the peak pulse current is 14.1A — that is the current the diode can handle before the clamping voltage rises to 35.5V. No power line protection (the device is not designed for AC mains) — it targets signal and DC rail protection where the surge energy is moderate. Microchip lists the SMAJ22CAE3/TR13 as Active. No LTB notice or successor has been published, so this BOM line is safe for production builds.","metaTitle":"SMAJ22CAE3/TR13 TVS Diode – 22V Standoff, 500W","metaDescription":"Microchip SMAJ22CAE3/TR13 Zener TVS: 22V reverse standoff, 35.5V clamping, 500W peak pulse power, bidirectional, DO-214AC (SMA).
