Breakdown triggers at a minimum of 56.7 V, clamping the overvoltage event and limiting the peak at 82.4 V when the peak pulse current of 18.2 A flows through the device. ## Package and thermal environment The maximum junction temperature of 150 °C with an operating range down to -55 °C covers both the cold-start extremes and the elevated ambient conditions found in industrial or outdoor enclosures. Since this is a unidirectional single-channel device, it protects one polarity only — a second device reversed is required for bidirectional AC-line protection. ## Series positioning and sourcing posture The 1.5SMCJ series is Panjit's 1.5 kW peak-pulse TVS family — variants span a range of standoff voltages, all sharing the same DO-214AB SMC package and tape-and-reel packaging.","metaTitle":"1.5SMCJ51A_R1_00001 Zener TVS Diode 51V 82.4V 1.5kW","metaDescription":"Panjit 1.5SMCJ51A_R1_00001 unidirectional Zener TVS, 51V standoff, 56.7V min breakdown, 82.4V clamping, 1.5kW peak pulse.
