It is obsolete per the manufacturer, so new designs should look at current-generation Vishay TVS parts in the same TransZorb family. For existing BOMs, we source it through independent supply — confirmed genuine, lot-traceable, and quoted per RFQ. ## What the ratings mean for your protection scheme The 60.7 V reverse standoff is the maximum continuous DC voltage the diode lets pass without conducting — a 48 V nominal battery bus or a 60 V power rail sits safely below this threshold. Breakdown starts at 67.5 V min, so the diode begins shunting just above the normal operating ceiling. Clamping at 109 V max under the 13.9 A peak pulse current means the downstream circuitry must survive that voltage for the 10/1000 µs pulse duration. The 1500 W peak pulse rating is the product of clamp voltage and peak current — a standard metric for comparing TVS energy-handling across the 1.5KE series. The AEC-Q101 qualification means it passed the automotive stress tests — temperature cycling, high-temperature reverse bias, and ESD robustness per the standard. ## Through-hole package — field-swappable without a hot-air station The DO-201AA axial-lead package (also known as DO-27) is a through-hole form factor that can be swapped on site with a standard soldering iron — no hot air or reflow profile needed. The long leads and robust body make it a good fit for point-to-point wiring or terminal-block mounting in industrial control panels and automotive junction boxes. ## Sourcing an obsolete automotive TVS Vishay lists the 1.5KE75CHE3/54 as obsolete. For a BOM that already specifies this part, we source through independent distribution — units are verified genuine, RoHS-compliant, and lot-traceable.","metaTitle":"1.5KE75CHE3/54 Vishay TVS, 1500W, 60.7V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE75CHE3/54 TransZorb TVS, AEC-Q101 automotive, 1500W peak pulse, 60.7V standoff, 109V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"Automotive, AEC-Q101, TransZorb®","Package":"Tape & Reel (TR)","Applications":"Automotive","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":"1.5KE75","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"67.5V","Voltage - Clamping (Max) @ Ipp":"109V","Voltage - Reverse Standoff (Typ)":"60.7V","Current - Peak Pulse (10/1000µs)":"13.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1.5KE75CHE3/54 obsolete?","answer":"Yes, Vishay lists this part as obsolete.
