The reverse standoff voltage of 89.2V means it starts conducting above that DC level, clamping at 158V max at the rated 9.5A peak pulse current. The 99V minimum breakdown point gives a tight guard band above the 89.2V standoff, so the protected rail sees minimal overvoltage before the device turns on. ## Lifecycle reality — obsolete, last-time-buy window closed Vishay has marked the 1.5KE110HE3/54 as Obsolete. This means the manufacturer's last-time-buy window has passed, and new production lots are no longer available from Vishay's factory channel. Sourcing now runs through independent distribution and surplus inventories. For a BOM that requires this exact order code, the supply posture is quoted-to-order — availability, pricing, and date-code range are established when the request is placed. Housed in a DO-201AA (DO-27) axial-leaded package, the 1.5KE110HE3/54 mounts through-hole. The axial body with formed leads suits point-to-point wiring, terminal block termination, or PCB insertion with a 1.0mm diameter lead. The Tape & Reel packaging indicates it was originally supplied for automated insertion — bulk or cut-tape available from surplus stock.","metaTitle":"1.5KE110HE3/54 Vishay TVS, 1500W, AEC-Q101, Obsolete","metaDescription":"Vishay 1.5KE110HE3/54 unidirectional Zener TVS, 1500W peak pulse, 89.2V standoff, DO-201AA.
