The 1500W peak pulse power means it can absorb a 25.3A surge for the standard 10/1000µs waveform before the junction temperature hits the limit. The DO-214AB (SMC) package is surface-mount, with the cathode band marking the unidirectional orientation.","metaTitle":"Vishay 1.5SMC43A-E3/57T TVS Diode, 1500W, 36.8V Standoff","metaDescription":"Vishay 1.5SMC43A-E3/57T Zener TVS diode, 1500W peak pulse power, 36.8V reverse standoff, unidirectional, DO-214AB SMC.
