The 64.1 V reverse standoff sets the working rail below which the TVS stays off and leaks only microamps; anything above it begins to avalanche. ## Standoff, breakdown, and the protection window The 64.1 V reverse standoff is the continuous working voltage — the TVS sits in parallel with the rail and draws only leakage current while the line stays below this threshold. When a surge exceeds the 71.3 V minimum breakdown, the Zener avalanche kicks in and the device transitions from high-impedance off to low-impedance clamping. The gap between 64.1 V and 71.3 V is the design margin — the wider it is, the more headroom the protected circuit has before the TVS fires on normal transients. ## Operating temperature and DO-214AB SMC package The DO-214AB (SMC) surface-mount package is the mid-size TVS package — larger than SMB, smaller than SMD — which means a reasonable die attach area and thermal path without the board footprint of a full 600 W part. Pb-free finish supports RoHS assembly flow.","metaTitle":"1.5SMC75A BK PBFREE Central Semiconductor TVS Diode 103V","metaDescription":"Unidirectional Zener TVS diode, 64.1 V standoff / 71.3 V min breakdown / 103 V clamping, 1.5 kW peak pulse, DO-214AB SMC.
