Product details

Automotive-grade transient suppression for 36.8 V rails

The 1.5SMC43CAHM3/I: The device clamps at 59.3 V maximum at the rated 25.3 A peak pulse current, with a minimum breakdown voltage of 40.9 V. This clamping margin keeps downstream semiconductors within their safe operating area during load-dump or inductive kickback events.

AEC-Q101 qualification and temperature range

AEC-Q101 qualification means this part has passed the automotive-grade stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness per the standard. The DO-214AB (SMC) surface-mount package supports standard reflow soldering profiles. The bidirectional configuration uses a single die in a two-terminal package, simplifying PCB layout for a single-rail clamp.
