Product details

1500 W peak pulse, 145 V standoff — the protection envelope

The 1.5SMC170CA-E3/57T: The bidirectional configuration (one device, two symmetrical Zener junctions in series) means polarity does not matter — it clamps equally on positive and negative surges, which simplifies board layout for AC-coupled or floating signal lines.

DO-214AB footprint and temperature range

Housed in a DO-214AB (SMC) surface-mount package, the device operates from -65 °C to 150 °C junction temperature. The wide temperature range suits outdoor or industrial enclosures where ambient heat and self-heating from repetitive surges stack the thermal budget.
