When it fires, the clamping voltage holds at 113 V maximum at the rated 13.3 A peak pulse current. That 113 V ceiling determines whether the downstream silicon — an SMPS controller, a DC-DC input, a sensor bus — survives the surge without secondary breakdown. ## Active production, single-channel unidirectional protection The device is a single-channel unidirectional suppressor, meaning it protects one rail against positive-going transients with respect to ground. The DO-214AB (SMC) package is a standard surface-mount footprint for this power class, with the cathode tab on the larger pad for thermal transfer to the PCB copper. ## Where it fits in the protection scheme With a 70 V standoff, this part is sized for 48 V nominal rails (telecom, PoE, industrial bus supplies) and 60 V systems where the steady-state voltage stays below the standoff. The -55°C to +150°C junction temperature range covers outdoor and under-hood environments — the TVS does not derate significantly until the ambient pushes past 125°C. Power line protection is marked as No — this is a signal- or low-power-rail suppressor, not a primary mains protector. In a typical application it sits after the input fuse and rectifier, shunting the clamped energy to ground before it reaches the downstream converter.","metaTitle":"Diodes Inc SMCJ70A-13-F TVS Diode, 1500W, 70V Standoff","metaDescription":"SMCJ70A-13-F Zener TVS diode, 1500W peak pulse power, 70V reverse standoff, 113V clamping.
