A 5 V supply rail with 10 % tolerance (5.5 V max) stays below this standoff, so the diode does not leak or wear in normal operation. The 7.13 V minimum breakdown voltage (the point where the Zener junction starts conducting) sits between the standoff and the clamp — the TVS transitions from high-impedance to low-impedance in this window, shunting the surge current to ground. ## Temperature range and package — through-hole axial for board-level retrofit The device is not rated for power-line protection (Power Line Protection: No) — it is designed for secondary-side DC rail clamping, not AC mains surge suppression. ## Active lifecycle — stocked and quoted per RFQ Vishay lists the 1.5KE7.5A-/54 as Active.","metaTitle":"Vishay 1.5KE7.5A-E3/54 TransZorb TVS, 1500W, 6.4V Standoff","metaDescription":"Vishay 1.5KE7.5A-E3/54 TransZorb Zener TVS diode, 1500W peak pulse, 6.4V reverse standoff, DO-201AA axial.
