The CA suffix denotes a bidirectional (symmetric) configuration — a single bidirectional TVS replaces two back-to-back unidirectional devices on AC rails, saving a footprint slot in the layout. ## Board-fit and thermal envelope DO-214AB (SMC) is the standard surface-mount package for 1500 W TVS parts — the cathodic tab area under the body is the primary thermal conduction path to the board pad; adequate solder wetting and pad geometry matter more than any added heatsink for repetitive-pulse duty. Junction temperature rating is -55 to 150 °C, so the part covers both the cold end of outdoor equipment and the elevated-ambient conditions inside enclosed panels without derating the clamping performance for a one-shot surge event. Shipped on Tape & Reel — compatible with standard SMT pick-and-place line speeds for this package size without any special feeder modification.","metaTitle":"1.5SMC82CA R7G TVS Diode, 113V Clamping, 13.9A Peak","metaDescription":"Taiwan Semiconductor 1.5SMC82CA R7G — 1.5 kW unidirectional TVS Zener, 70.1V standoff / 113V clamping, DO-214AB SMC, -55 to 150°C.
