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.","metaTitle":"1.5SMC82CA-M3/57T TVS Diode 1500W 113V Clamping","metaDescription":"Vishay 1.5SMC82CA-M3/57T bidirectional TVS Zener, 1500W peak pulse, 113V clamping.
