Product details

1.5 kW Zener TVS for automotive and telecom bus protection

The 1.5SMC39AHM3/H: It is qualified to AEC-Q101, making it suitable for automotive electronics where reliability screening per the PPAP process is required.

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. The TransZorb® construction delivers low clamping factor and fast response to transients, which is critical for protecting sensitive ECU, sensor, and infotainment bus lines from load-dump and inductive kickback events.

Package and board-fit considerations

The copper pad area under the cathode tab sets the thermal resistance — for the full 1500 W pulse, the PCB copper area should follow the Vishay application note derating curve.

Frequently asked questions

What compliance documentation does Vishay provide for this part?

As an AEC-Q101 qualified device, Vishay provides PPAP documentation, RoHS compliance data, and REACH declaration upon request through the supply chain. The part is designed for automotive and telecom applications.
