Bidirectional construction (one channel) means the clamping characteristic is symmetrical — the same breakdown and clamp voltages apply for positive and negative transients. This makes it suitable for AC signal lines or bipolar DC rails where the polarity of the surge is unknown. The 150°C TJ(max) also gives margin for self-heating during repetitive surge events. Supplied on tape and reel, the 1.5SMC51CA R7G is ready for high-volume pick-and-place assembly. For current BOMs, this part is a low-risk, production-available line item. No stock-holding claim is made; the part is quoted to order.","metaTitle":"1.5SMC51CA R7G TVS Diode, 1500W, 43.6V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC51CA R7G bidirectional TVS diode, 1500W peak pulse, 43.6V reverse standoff, 70.1V clamping.
