The gap between standoff and breakdown gives the protected rail ~8 V of differential before the TVS activates — enough to let normal operation sit clean without the clamp eating rail noise on a 48 V system.","metaTitle":"1.5SMCJ70 TVS Diode, 70V Standoff, 1.5 kW Peak","metaDescription":"Diotec 1.5SMCJ70 unidirectional TVS diode, 70 V standoff, 125 V clamping, 12 A peak pulse, DO-214AB SMC surface mount.
