Product details

1.5kW bidirectional TVS for 171V rails

The 1.5SMC200CAHM3_A/H: The 274V clamp ceiling keeps the protected node below the typical 300V breakdown of downstream electrolytic capacitors and MOSFETs.

AEC-Q101 qualified, this TVS is screened for automotive-grade reliability — temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive stress test suite.

DO-214AB (SMC) package and board integration

Housed in a DO-214AB (SMC) surface-mount package, the device has a standard footprint with a cathode band for orientation — though as a bidirectional part, polarity is not critical. The SMC body is larger than the SMA/SMB siblings, which translates to lower thermal resistance to the PCB copper pad for the same 1.5kW rating. The reel quantity is typically 3000 or 5000 pieces for the SMC package — confirm the reel count with the distributor at quote time to match the production batch size.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5SMC200CAHM3_A/H in this Circuit Protection family?

The base product number is 1.5SMC200, and the 1.5SMC series includes unidirectional and bidirectional variants at the same standoff voltage — but a pin-compatible alternative from another manufacturer is not confirmed. For a BOM hedge, request a parametric cross-search at RFQ time.
