The reverse standoff voltage of 9.72V typ means the diode stays high-impedance below that level, so a nominal 12V rail with normal ripple does not see leakage. Breakdown starts at 10.8V min, clamping at 17.3V max — the window between standoff and clamp is tight enough to protect a 12V-rated IC without nuisance triggering. ## Obsolete — sourcing through surplus channels Vishay lists the 1.5KE12C-/54 as obsolete. The base product number 1.5KE12 identifies the voltage family; the suffix variant (C for bidirectional, for RoHS) is the only differentiator. ## Temperature range and mounting The DO-201AA (DO-27) axial lead package is through-hole, suited for point-to-point wiring or PCB mounting with 0.040-inch diameter leads. The wide temperature envelope means derating is minimal even in a sealed enclosure near a hot power supply. No power line protection feature — this is a signal or low-power rail protector, not a mains-grade MOV replacement.","metaTitle":"Vishay 1.5KE12C-E3/54 TransZorb TVS, 1500W, 86.7A","metaDescription":"Vishay 1.5KE12C-E3/54 bidirectional Zener TVS diode, 1500W peak pulse, 86.7A @ 10/1000µs, DO-201AA.
