Peak pulse power is rated 500W under the 10/1000µs waveform, with a clamping voltage of 21.5V at the peak pulse current of 23.2A. That 500W rating is the headline number for surge sizing — derate it against the operating temperature and the number of expected transients. Single bidirectional channel means one device protects both polarities on a signal or power line — no need to pair two unidirectional parts back-to-back.","metaTitle":"SMAJ13CAE3/TR13 TVS Diode – Microchip, 500W Bidirectional","metaDescription":"SMAJ13CAE3/TR13 Zener TVS, 13V reverse standoff, 21.5V clamp, 500W peak pulse, bidirectional, DO-214AC.

It clamps transients of either polarity on the protected line, so one device replaces two unidirectional TVS diodes in back-to-back configuration."},{"question":"What is the closest pin-compatible alternative?","answer":"Any SMAJ13CA (bidirectional, 13V standoff, 500W) in DO-214AC from a different brand — for example, Littelfuse or Vishay — is functionally equivalent. The footprint is standard SMA, so no board change is needed.
