When a transient exceeds the breakdown threshold, the clamping voltage ceiling is 77.4 V, which is the maximum stress the downstream circuit sees during the event. The peak pulse rating of 1500 W at a 10/1000 µs waveform corresponds to a peak clamping current of 19.4 A — the current the TVS must safely dissipate as heat during a single transient spike. The DO-214AB (SMC) package thermal impedance determines how quickly the junction recovers between events. A junction temperature rating of -50°C to 150°C places this part in the industrial-grade band — suitable for enclosures and factory-floor environments where transient suppression is specified without active cooling. The unidirectional configuration (one bidirectional channel,) guards a single polarity rail; a complementary pair handles dual-rail designs. Listed as Active under Diotec Semiconductor. General-purpose Zener TVS diodes in this voltage and power class are routinely stocked by multiple sources — confirm the standoff, clamping, and peak pulse ratings against the existing BOM tolerance before specifying a second-source alternative.","metaTitle":"Diotec 1.5SMCJ48CA, 48 V Zener TVS Diode, 77.4 V Clamping","metaDescription":"Diotec 1.5SMCJ48CA Zener TVS diode, 48 V standoff, 53.3 V min breakdown, 77.4 V clamping, 1500 W peak pulse, bidirectional, DO-214AB SMC.
