Product details

Device identity and key ratings

The 1.5SMC22CAHM6G: The DO-214AB (SMC) surface-mount package handles the 1500W pulse without cracking the epoxy, provided the PCB copper area under the cathode tab is sized for the thermal impulse.

Sizing the clamp for your rail

The 20.9V minimum breakdown voltage guarantees the avalanche triggers before the clamping voltage is reached, and the 30.6V clamp is the voltage the protected IC sees during the pulse — a 30V-rated MOSFET on the rail has margin.

As an AEC-Q101 qualified device, it ships with full lot traceability and compliance documentation — RoHS and REACH declarations are standard with the shipment.

Frequently asked questions

What is the closest alternative to 1.5SMC22CAHM6G in the same family?

The bidirectional version is the 1.5SMC22CA; the HM6G suffix denotes the AEC-Q101 automotive grade and the specific packaging configuration. A non-automotive equivalent would be the standard 1.5SMC22CA without the HM6G suffix, but the pinout and footprint are identical.

What compliance documentation does Taiwan Semiconductor provide for this part?

As an AEC-Q101 qualified device, the 1.5SMC22CAHM6G ships with RoHS and REACH compliance declarations. Full lot traceability and a certificate of conformance are available with each shipment.
