Product details

The Bourns 1.5SMC30A-Q is a Zener-type TVS diode from the 1.5SMC-Q series, qualified to AEC-Q101 for automotive applications.

Automotive-grade transient protection

AEC-Q101 qualification means this part has passed the full suite of automotive stress tests — temperature cycling, high-temperature reverse bias, and ESD robustness — making it suitable for under-hood and cabin electronics where reliability is non-negotiable. The copper leadframe and large die attach handle the 1500 W pulse without exceeding the junction temperature limit, provided the PCB copper area under the package is adequate for heat sinking.
