It clamps at 103V maximum with a 64.1V reverse standoff, meaning it holds off a 64V rail and starts conducting above 71.3V breakdown. This is a unidirectional device — one channel, cathode band on the body — in a DO-201AD axial-lead package for through-hole mounting. The -65°C to 175°C junction temperature range suits it for environments where the ambient runs hot — think industrial power supplies, motor drives, or outdoor telecom cabinets where the board sees wide thermal swings. ## Clamping Voltage and Pulse Current — What They Mean for Your Rail With a 64.1V reverse standoff and 71.3V minimum breakdown, this part protects a nominal 48V or 60V bus without clipping normal ripple. The 103V maximum clamp at 14.6A peak pulse current tells you the voltage the load sees during a surge — if your downstream circuitry cannot survive 103V for the 10/1000µs pulse, you need a lower-clamp part or a multi-stage protector. The 1500W rating is the peak pulse power at the specified waveform; derate for higher ambient temperature per the datasheet curve. No power line protection — this is a signal-rail or DC-bus clamp, not a mains surge suppressor. ## Obsolete — Sourcing and Replacement Planning onsemi lists the 1.5KE75AG as Obsolete. For a drop-in replacement in the same DO-201AD footprint, look at the 1.5KE75A from other major TVS manufacturers — Littelfuse, Vishay, and ST all offer functionally equivalent parts with the same 1500W rating, 64.1V standoff, and 103V clamp. Confirm the breakdown tolerance and surge capability match your BOM requirement before swapping. Because this part is end-of-life, we source it per RFQ against your BOM quantity. If you are qualifying a new design, skip the obsolete part and select a current-production 1.5KE-series TVS from the same footprint family.","metaTitle":"1.5KE75AG Zener TVS Diode – 1500W, 64.1V Standoff, DO-201AD","metaDescription":"onsemi 1.5KE75AG Mosorb™ Zener TVS, 1500W peak pulse power, 64.1V reverse standoff, 103V clamping.
