Its 71.3 V minimum breakdown voltage ensures the device stays off during normal operation, while the 103 V maximum clamping at 14.6 A peak pulse current (10/1000 µs waveform) limits overvoltage stress on downstream silicon. ## 1500 W peak pulse — what it means for your BOM Rated at 1500 W peak pulse power for a 10/1000 µs waveform, this part handles transient energy that would otherwise damage ICs on a 64 V bus. The through-hole DO-201AD axial package allows the heat to be conducted into the PCB traces or a heatsink — the junction temperature range of -65°C to 175°C covers industrial and some automotive under-hood environments, though it is not formally AEC-Q101 qualified. ## Obsolete — sourcing and replacement planning onsemi has marked the 1.5KE75ARL4 as Obsolete. For existing BOM lines, confirm the exact breakdown and standoff voltages; a slightly higher or lower clamp voltage may be acceptable depending on the downstream device's absolute maximum rating.","metaTitle":"1.5KE75ARL4 onsemi Zener TVS Diode — 1500W, DO-201AD","metaDescription":"onsemi 1.5KE75ARL4 Zener TVS diode, 1500W peak pulse, 64.1V standoff, 71.3V breakdown, 103V clamp.
