The 1500W peak pulse rating assumes a 10/1000µs waveform at 25°C ambient. Derate linearly above 25°C per the datasheet curve — at 125°C the peak pulse power drops to roughly 60% of the 1500W figure, so a 900W effective rating is the safe design-in number for high-temperature environments. No pin-compatible second source is recorded — the TransZorb series is Vishay's own die and passivation process.","metaTitle":"1.5KE22CA-E3/73 TVS Diode, 1500W, 18.8V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE22CA-E3/73 bidirectional TVS diode, 1500W peak pulse, 18.8V reverse standoff, DO-201AA axial.
