Product details

1.5kW bidirectional TVS — AEC-Q101 qualified for 12V/24V automotive buses

The 1.5SMC30CAHM3/I: It clamps transients on 12V and 24V vehicle power buses, telecom lines, and industrial DC rails where a single device must survive a 1.5 kW peak pulse (10/1000 µs waveform) without failing short.

Clamping, breakdown, and standoff — the protection window

The bidirectional channel means a single DO-214AB (SMC) component protects both polarities, simplifying layout on AC-coupled or bipolar signal lines where the surge can swing either direction.

AEC-Q101 and operating range — under-hood and beyond

AEC-Q101 qualification means the device has passed the automotive stress suite: temperature cycling, high-temperature reverse bias, and ESD robustness. Surface-mount DO-214AB (SMC) package with a standard footprint — the same pad pattern used across the 1.5SMC family, so a BOM change to a different standoff voltage requires no board layout revision.

Frequently asked questions

What compliance documentation does Vishay provide for this TVS diode?

As an AEC-Q101 qualified device, Vishay provides automotive-grade PPAP documentation, RoHS compliance data, and a radiation characterization report upon request through the supply chain. The part is also REACH compliant per Vishay's standard declaration.

What is the peak pulse power rating and what does it mean for circuit protection?

This means it can absorb a transient surge of that energy without failing, making it suitable for protecting sensitive electronics on automotive load-dump or lightning-induced transients on telecom lines.
