That clamping voltage is the voltage the downstream circuitry must survive — if your 24V-rated ICs have a 30V abs-max, this TVS keeps them inside the safe zone. ## Active production — no last-time-buy pressure The TransZorb series is Vishay's established TVS diode family, widely second-sourced across the industry. For BOM resilience, the 1.5KE20A electrical parameters (17.1V standoff, 19V breakdown, 27.7V clamp) are common across multiple manufacturers — a cross-reference can be qualified during prototype if dual-sourcing is required. ## Through-hole DO-201AA — board integration Housed in a DO-201AA (DO-27) axial-lead package, the device is through-hole mounted. The lead spacing and body diameter are standard for this power level — the board footprint is the same as other 1.5KE-series parts, so a single PCB layout serves multiple voltage variants. The wide range means the clamping voltage and leakage current remain predictable across the thermal extremes of a motor drive or outdoor telecom cabinet.","metaTitle":"1.5KE20A-E3/54 Vishay TVS Diode, 1500W, 27.7V Clamp","metaDescription":"Vishay 1.5KE20A-E3/54 TransZorb TVS diode, 1500W peak pulse, 27.7V clamp, 17.1V standoff, DO-201AA axial.
