In a typical 214V bus application, the device breaks down at 237V minimum and clamps at 344V maximum, shunting 5A of surge current away from the load. The wide operating temperature range of -65°C to 175°C makes it suitable for outdoor, industrial, or under-hood environments where thermal cycling is a concern. ## Obsolete – last-time-buy window closed onsemi has marked the 1.5KE250AG as Obsolete. For existing BOMs, procurement should verify date-code authenticity and source from verified inventory through an RFQ. The DO-201AD axial package is widely used in through-hole designs, so a form-fit-function replacement from the same 1.5KE series or another manufacturer's TVS portfolio is the practical path forward. ## Package and mounting – DO-201AD axial The part comes in a DO-201AD axial-lead package, through-hole mount. The axial form factor is straightforward for hand-soldering or wave-solder rework; lead bending for board standoff is common. The package is, so reel or tape quantities are not an option for automated pick-and-place.","metaTitle":"1.5KE250AG onsemi Zener TVS Diode – Obsolete, Sourcing Info","metaDescription":"onsemi 1.5KE250AG Mosorb™ Zener TVS, 1500W peak pulse, 214V reverse standoff, DO-201AD.
