Any stock found will carry the original Vishay date-code and marking; the laser etch and package consistency should be verified against the TransZorb family standard before committing to a large buy. ## Clamping ratings and protection fit This is a 1500 W (1.5 kW) bidirectional Zener TVS diode in the TransZorb series. The 21.8 V reverse standoff voltage means the device does not conduct below that rail — it sits across a 21.8 V or lower supply line without leakage. The 1500 W rating is the peak pulse power dissipation into that waveform; real-world derating applies above 25 °C ambient. ## Package and temperature envelope Through-hole axial package (DO-201AA / DO-27) — the body is the same diameter as the standard 1.5KE series. The bidirectional single-channel configuration means a single device clamps both polarities, saving a diode in the protection stage.","metaTitle":"1.5KE27C-E3/73 Vishay TransZorb Zener TVS, 1500W, 21.8V","metaDescription":"Vishay 1.5KE27C-E3/73 TransZorb bidirectional Zener TVS, 1500W peak pulse, 21.8V standoff, 38.4A Ipp. Obsolete — sourced to order.
