It clamps a 6.4 V rail at 14.5 V when the surge hits, with a minimum breakdown of 7.13 V. The 690 A peak pulse current rating (8/20 µs waveform) tells you this was designed for industrial power-supply and heavy-equipment rail protection, not for signal-line ESD. ## Obsolete — no active production, sourced through surplus STMicroelectronics lists the 1.5KE7V5ARL as Obsolete. The closest functional equivalent within the same 1.5KE family is the 1.5KE7V5A — same 1500 W rating, same breakdown and clamping voltages, same DO-201 package. For BOM lines that need a drop-in replacement, the 1.5KE7V5A is the part to qualify. ## DO-201 axial — through-hole mounting, board-level retrofit Package is DO-201AA / DO-27 axial lead, through-hole mount. The 8500 pF capacitance at 1 MHz is typical for a 1.5 kW TVS — expect this to load high-speed data lines; it is meant for DC power rails and low-frequency protection, not for Ethernet or USB. Power line protection is not supported, per the spec.","metaTitle":"1.5KE7V5ARL Zener TVS Diode, 1500W, DO-201, Obsolete","metaDescription":"1.5KE7V5ARL is a 1500W unidirectional Zener TVS from the 1.5KE/TRANSIL™ series.
