Transient protection at 1.5 kW peak
The 1.5SMC82CA-M3/57T: With a 70.1 V typical reverse standoff, the diode stays off normal operating rails up to that level and turns on only when a transient exceeds the 77.9 V minimum breakdown — the gap between 70.1 V standoff and 77.9 V breakdown gives roughly 7.8 V of headroom before the device begins conducting. The single bidirectional channel means it suppresses transients of either polarity without a second device — suited for AC rails, communication lines, or any node where polarity is not fixed.
DO-214AB SMC mount and thermal margin
Surface-mount DO-214AB (SMCJ) package in Tape & Reel — the wide cathode tab gives the transient suppressor its thermal path to the PCB copper; adequate pad coverage under the tab matters more than the package itself for pulse handling. Classified as general-purpose on the application side — it protects rails and nodes in power supplies, consumer electronics, and industrial controls where the voltage band and peak pulse energy fall within the 1.5 kW ceiling.
