Mosorb™ series, Zener TVS diode, 1.5KE62AG, 1500W peak pulse power, 53V reverse standoff, 85V clamping, DO-201AD axial, through-hole.","salesMarkdown":"## 1500W Zener TVS — 53V standoff, 85V clamp The 1.5KE62AG is a 1500 W peak pulse power Zener TVS diode from Littelfuse's Mosorb™ series, designed to clamp transient overvoltage events on a 53 V nominal rail. The 53 V reverse standoff voltage means the diode does not conduct at the nominal bus voltage — it sits transparently across the rail until a transient pushes the line above the 58.9 V breakdown threshold. The 85 V clamp ceiling limits the voltage the protected load sees, keeping it within the safe operating area of downstream 75 V or 100 V rated parts. ## Obsolete — last-time-buy sourcing through independent channels Littelfuse has marked the 1.5KE62AG as obsolete. The part is no longer available through authorized distribution channels for new production. For sustainment programs, repair depots, or legacy BOM fills, the 1.5KE62AG is sourced through independent surplus and broker channels. Each lot is verified for traceability and authenticity before shipment. Availability and pricing are confirmed at RFQ against the specific quantity required — no blanket stock claim is made. ## DO-201AD axial package — board-fit and thermal considerations The operating junction temperature range spans -65°C to 175°C, covering military and industrial thermal environments. The wide temperature envelope means the clamping voltage shifts with temperature — the datasheet's typical temperature coefficient for Zener breakdown applies — but the 85 V maximum clamp at 25°C remains the design-in ceiling for the protected rail.","metaTitle":"1.5KE62AG Littelfuse Mosorb Zener TVS, 1500W, 53V","metaDescription":"Littelfuse 1.5KE62AG Mosorb Zener TVS diode, 1500W peak pulse, 53V reverse standoff, DO-201AD axial.
