Product details

AEC-Q101 TVS for 400V automotive bus protection

The Vishay 1.5SMC400AHE3_AIH is a unidirectional Zener-type TVS diode from the TransZorb® family, qualified to AEC-Q101 for automotive-grade reliability.

DO-214AB SMC package and board integration

The package footprint is shared with the SMCJ industry-standard outline — the supplier device package is listed as DO-214AB (SMCJ) — so existing board layouts for a 1500W TVS in this form factor accept the part without a pad revision.

Listed as Active in production status.
