Product details

1500W peak pulse, AEC-Q101 Zener clamp

The 1.5SMC10AHM3/H: With an 8.55V reverse standoff voltage, this device protects 5V, 9V, or 12V rails in automotive ECUs, engine control modules, and telecom line cards where a single unidirectional Zener clamp is sufficient.

AEC-Q101 qualification and junction temperature range

The junction temperature range spans -65°C to 150°C, covering under-hood and engine-bay thermal profiles. The DO-214AB (SMC) package is a surface-mount footprint with a large copper pad on the cathode side for heat sinking. The 1500W peak pulse rating assumes the standard JEDEC 10/1000µs waveform; derate power linearly above 25°C per the datasheet curve.

Active production and sourcing posture

Tape & Reel packaging suits automated pick-and-place assembly. The base product number 1.5SMC10 covers the unqualified variant; the HM3/H suffix denotes the AEC-Q101 automotive grade and Vishay's halogen-free, RoHS-compliant finish.

Frequently asked questions

What compliance documentation does Vishay provide for 1.5SMC10AHM3/H?

As an AEC-Q101 qualified device, Vishay provides a PPAP (Production Part Approval Process) package upon request, along with RoHS and halogen-free compliance declarations. The HM3/H suffix specifically indicates the halogen-free, RoHS-compliant finish.
