The 56A peak pulse current rating tells you the surge current the part can handle before the junction temperature exceeds the 150°C limit. For a given surge, the actual clamping voltage is the sum of the breakdown voltage plus the dynamic resistance times the surge current — the 27.7V max at Ipp is the worst-case ceiling. The copper pad area under the package sets the thermal resistance — a larger cathode tab pad pulls heat into the board plane and keeps the junction temperature rise within limits during repetitive surges. ## Active lifecycle and sourcing The Tape & Reel packaging (standard for the series) supports automated pick-and-place assembly.","metaTitle":"1.5SMC20CA V7G TVS Diode, 1500W, 27.7V Clamp, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC20CA V7G bidirectional Zener TVS, 1500W peak pulse, 27.7V clamping, 17.1V standoff, DO-214AB SMC.
