1500 W peak pulse, 94 V standoff — the protection threshold for 12 V / 24 V automotive buses
The 1.5SMC110CAHE3/9AT: The -65 to 150 °C junction temperature range covers the full automotive ambient envelope with margin.
Breakdown and clamping — where the avalanche triggers
Minimum breakdown voltage is 105 V; the device starts conducting in avalanche mode once the transient exceeds this level. The 152 V max clamping voltage at 9.9 A defines the voltage the downstream circuitry sees during a surge — a 24 V ECU rated for 40 V absolute maximum has ample headroom. No power-line protection rating confirms this is a DC-rail or signal-line TVS, not an AC mains suppressor.
Package and board-fit — DO-214AB (SMC) surface mount
Housed in the DO-214AB (SMC) package, the same footprint as the standard SMCJ series. The base product number is 1.5SMC110, so the same die is available in other package or polarity variants under that root.
Active production — no lifecycle risk for new designs
Product status is Active — Vishay continues to manufacture this order code.
