The 53 V reverse standoff voltage means the part does not conduct at normal DC bus levels up to that point. Breakdown starts at 55.8 V minimum, so on a 48 V nominal rail the diode sits transparent until a transient pushes the line above the threshold. ## Bidirectional clamping and package reality A single bidirectional channel handles surges of either polarity — useful on AC signal lines or DC rails where the transient can swing positive or negative relative to ground. No need for two diodes back-to-back. ## Obsolete — sourcing through independent channels Littelfuse has marked the 1.5KE62C as obsolete. The part is no longer available through the factory or authorized distribution channel. We source this part through independent surplus and broker channels. Each lot is visually inspected and verified against the manufacturer's marking specification — the laser etch, date-code font, and package dimensions are checked before the material is offered.","metaTitle":"1.5KE62C Littelfuse TVS Diode, 1500W Bidirectional, DO-201","metaDescription":"Littelfuse 1.5KE62C bidirectional TVS diode, 1500W peak pulse power, 53V standoff, 89.25V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5KE","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"55.8V","Voltage - Clamping (Max) @ Ipp":"89.25V","Voltage - Reverse Standoff (Typ)":"53V","Current - Peak Pulse (10/1000µs)":"17.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7081","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the 1.5KE62C?","answer":"No pin-compatible successor is listed by Littelfuse.
