Product details

Clamp voltage and surge rating for 25.6V rails

The 1.5SMC30AHM3_A/H: Its 25.6V reverse standoff voltage protects 24V nominal rails, clamping transients at 41.4V maximum while conducting 36.2A peak pulse current. The 28.5V minimum breakdown voltage ensures the device stays out of conduction during normal 24V system ripple, while the 41.4V clamp keeps the protected node below typical downstream component abs-max ratings for 40V-tolerant parts.

Automotive qualification and temperature range

AEC-Q101 qualification means this part has passed automotive-grade reliability stress tests including high-temperature reverse bias, temperature cycling, and ESD immunity per the automotive electronics council standard. Target applications include automotive electronic control units, telecom line cards, and general-purpose transient suppression where 1500W peak pulse capability is needed in a surface-mount DO-214AB footprint.

DO-214AB package and reflow considerations

The tape-and-reel packaging (TR) suits high-volume pick-and-place assembly. No power line protection feature is built in — this is a unidirectional TVS for signal or low-side power rail clamping, not for AC mains. The single-channel unidirectional design protects one rail per device.

Frequently asked questions

What does AEC-Q101 qualification mean for this part?

AEC-Q101 is the automotive discrete semiconductor qualification standard. It certifies the device has passed temperature cycling, high-temperature reverse bias, and ESD reliability tests required for automotive electronics deployment.
