Product details

The 1.5SMC180AHE3/57T is a Zener TVS diode in the DO-214AB (SMC) surface-mount package. The footprint matches the standard SMCJ land pattern — the cathode band is marked on the body. Reflow profile follows J-STD-020 for the 260 °C peak; the package is rated for -65 °C to 150 °C junction temperature.

Clamping and power rating

The reverse standoff voltage is 154 V, with a minimum breakdown of 171 V.

Automotive qualification and compliance

Part of the 1.5SMC TransZorb series, this diode carries AEC-Q101 automotive qualification — it is screened for the temperature, reliability, and PPAP requirements of automotive electronics. The series is marked as Automotive grade, suitable for under-hood and chassis-domain protection circuits.
