When the transient hits, the clamping voltage is held to 104 V maximum at the 14.6 A peak pulse current (10/1000 µs waveform). That 104 V ceiling is the voltage the downstream silicon sees — if the protected device's abs-max rating is above 104 V with margin, the TVS keeps it inside the SOA. ## Bidirectional clamping for AC or dual-polarity lines This makes the 1.5KE75CA-/54 a natural fit for AC signal lines, data pairs that swing below ground, or dual-polarity DC rails where two unidirectional parts would otherwise be needed back-to-back. The junction temperature range spans -55°C to 175°C, so the clamping performance holds across industrial cabinet ambients and under-hood engine bay conditions. The 1500 W peak pulse rating is derated above 25°C per the datasheet curve — at 125°C the effective power drops to roughly 750 W, which still covers most IEC 61000-4-5 surge levels at the secondary side. ## Through-hole mounting and package availability The DO-201AA (DO-27) axial leaded package is a standard through-hole form factor. The leads are tin-plated copper; the body is molded epoxy with the cathode band marked — for a bidirectional part the band is absent or replaced by a bidirectional symbol.","metaTitle":"1.5KE75CA-E3/54 Vishay TVS, 1500W, 64.1V Standoff","metaDescription":"Vishay 1.5KE75CA-E3/54 TransZorb® TVS diode, 1500W peak pulse, 64.1V standoff, 104V clamp, bidirectional, DO-201AA, active production.
