Product details

The 1.5SMC11A-M3/9AT: With a 9.4 V reverse standoff voltage and a minimum breakdown of 10.5 V, the device sits below a nominal 12 V rail without conducting during normal operation, then avalanches when the transient exceeds the breakdown threshold.

Package and temperature range for the board layout

The operating junction temperature range spans -65°C to 150°C, covering cold-start and under-hood environments without derating the peak pulse power at the high end.

Single-channel unidirectional — polarity matters on the board

This is a single unidirectional channel — the cathode band must face the protected rail, and the anode connects to ground. Reversing the polarity in a unidirectional TVS turns it into a forward-biased diode during a positive transient.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5SMC11A-M3/9AT in this Circuit Protection family?

The 1.5SMC series includes other voltage variants in the same DO-214AB footprint, but a different standoff voltage changes the protection threshold — confirm the rail voltage before substituting.

What compliance documentation does Vishay General Semiconductor - Diodes Division provide for 1.5SMC11A-M3/9AT?

Standard Vishay TVS documentation for the 1.5SMC series typically includes RoHS and REACH declarations — confirm at quote time if a specific certificate is required for your compliance audit.
