This is the class-leading surge rating for a through-hole axial part — the 132A peak pulse current gives a solid margin for clamping transients on 5V or 6V rails in industrial and telecom equipment. The reverse standoff voltage is 6.4V, meaning the part sits across a 5V or 6V supply without conducting until a surge pushes it above the 7.13V breakdown threshold. The clamping voltage is 11.3V at full rated current — enough headroom to protect downstream silicon rated for 12V or higher. ## Obsolete — Plan Your Sourcing Now onsemi has marked the 1.5KE7.5AG as Obsolete. For any BOM that still specifies this order code, the procurement path is either a last-time buy from remaining distributor stock or a qualified replacement from the same 1.5KE family. The base product number is 1.5KE, and the Mosorb™ series includes many active siblings. A direct functional replacement would be a unidirectional Zener TVS in DO-201AD with the same 6.4V standoff and 1500W rating — for example, the 1.5KE7.5A (without the G suffix) if still active, or a part from the Littelfuse or Vishay 1.5KE cross families. Confirm the clamping voltage and breakdown tolerance match your application before substituting. ## Temperature Range and Application Fit The 1.5KE7.5AG operates from -65°C to 175°C junction temperature — suitable for outdoor telecom cabinets, industrial motor drives, and automotive under-hood environments where the ambient can swing wide. The through-hole DO-201AD package is a legacy axial footprint; rework is straightforward with a soldering iron, but the lead spacing and body size must match the PCB hole pattern. Power line protection is not supported — this is a signal- or low-power-rail TVS, not a mains surge suppressor. The general-purpose application category covers DC power buses, I/O lines, and relay coil suppression in control panels and PLC I/O modules.","metaTitle":"1.5KE7.5AG onsemi Mosorb™ Zener TVS Diode – Obsolete","metaDescription":"onsemi 1.5KE7.5AG Zener TVS diode, 1500W peak pulse power, 6.4V standoff, DO-201AD axial.
