It provides a single bidirectional channel in a DO-214AB (SMC) surface-mount package. ## Peak pulse capability and clamping performance The clamp voltage is the ceiling the protected circuit sees — a downstream 24 V-rated component has margin above that level. The 74 A peak pulse current handling means the device absorbs substantial surge energy without failing short, which is the failure mode that would take the protected rail down. ## Board integration and temperature range Housed in a DO-214AB (SMC) package, the diode is surface-mount and suits reflow assembly. No power line protection feature is implemented — this is a standard TVS for signal and low-voltage DC bus clamping, not for AC mains surge suppression.","metaTitle":"1.5SMC15CA R7G TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC15CA R7G bidirectional TVS, 1500W peak pulse, 12.8V standoff, 21.2V clamp, DO-214AB.
