Product details

Active production – no LTB on the horizon

Bidirectional, 22V standoff, 35.5V clamp

This is a single-channel bidirectional Zener TVS. The 22V reverse standoff voltage means it sits across a 22V rail without conducting in normal operation. When a surge exceeds the 24.4V minimum breakdown, the device clamps at 35.5V maximum while shunting 42.2A peak pulse current in the 10/1000µs waveform. The 1500W peak pulse power sets the energy-handling ceiling — derate for higher ambient temperature per the datasheet curve.

DO-214AB (SMC) – board footprint and sourcing

The DO-214AB (SMC) package is a standard surface-mount footprint for 1.5kW-class TVS diodes. The tape-and-reel delivery suits automated pick-and-place.

Frequently asked questions

Is SMCJ22CAE3/TR13 bidirectional or unidirectional?

Bidirectional — a single Zener channel that clamps equally on positive and negative surges, so polarity on the protected line does not matter.

What is the closest pin-compatible alternative to SMCJ22CAE3/TR13 in this Circuit Protection family?

Any 22V bidirectional TVS in DO-214AB with a 1.5kW peak pulse rating is a functional equivalent. The SMCJ22CA (non- suffix) from Microchip or the SMCJ22CA from Littelfuse, Vishay, or Bourns share the same footprint and electrical window — confirm the standoff, breakdown, and clamp voltages match your rail before substituting.
