Product details

Bidirectional clamping at 113V

The 1.5SMC82CAHE3/57T is a bidirectional Zener-based Transient Voltage Suppressor (TransZorb®) — the two clamping polarities share a single 82V nominal rating.

1.5kW peak pulse in DO-214AB

Rated 1500 W peak pulse capacity, the 1.5SMC series absorbs surge energy in the DO-214AB (SMC) package — a common pick for automotive ECU input protection where board real estate is constrained and the clamping characteristic must stay within the downstream rail rating.

AEC-Q101 automotive qualification

The AEC-Q101 qualification means this part has passed the automotive stress sequence — temperature cycling, high-temperature reverse bias, and moisture resistance among others — at the device level rather than as a general-purpose commercial part. Junction temperature limit is 150°C with an operating range starting at -65°C, covering the cold-start to under-hood band.

Frequently asked questions

What voltage does this TVS actually clamp at during a surge?

The reverse standoff typ is 70.1 V — the TVS remains off below that level and conducts when the transient pushes the line above the breakdown threshold of 77.9 V minimum.

Is there a pin-compatible alternative in the same series?

The 1.5SMC series covers a range of standoff voltages in the same DO-214AB package, but no officially designated cross-reference or second-source order code appears in the current record for this exact 82V standoff variant.
