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. ## 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.
