Product details

What this 1500 W bidirectional TVS covers on a 24 V automotive bus

The 1.5SMC30CAHE3/9AT is a bidirectional Zener-type TVS diode from Vishay's 1.5SMC series, qualified to AEC-Q101 for automotive use. The bidirectional construction means it clamps both positive and negative transients, so no polarity worry when protecting AC-coupled or floating lines.

AEC-Q101 qualification and the operating envelope

An engine control unit or transmission sensor module that sees 125 °C ambient still has margin before the TVS derates. The supplier device package is listed as DO-214AB (SMCJ), meaning the same copper leadframe and solder pad layout as the SMCJ series — no board spin needed if you are migrating from a different 1500 W TVS in the same case.

Frequently asked questions

What does the 25.6 V reverse standoff voltage mean for a 24 V system?

The 25.6 V VRWM is the maximum DC voltage the TVS can block without conducting significant leakage. It protects the downstream electronics without wasting power during normal operation.

What compliance documentation is available for this part?

As an AEC-Q101 qualified device, Vishay provides PPAP (Production Part Approval Process) documentation, RoHS compliance data, and a full reliability report including ESD sensitivity and temperature cycling results. These are typically available from the manufacturer's documentation portal or through your distributor's compliance team.
