For a 12 V automotive bus, that leaves about 1.5 V of headroom before the TVS starts to avalanche. ## Automotive-grade qualification and temperature envelope The TransZorb series uses a passivated glass junction for high-temperature stability — leakage current stays controlled at the upper end of the range. ## Package and mounting — DO-201AA axial through-hole The leads are tin-plated copper, compatible with wave solder or hand-soldering. No moisture sensitivity level applies; no bake-out required before assembly. ## Lifecycle reality — obsolete, no direct successor Vishay has marked the 1.5KE15CAHE3/51 as obsolete. A pin-compatible functional replacement would require a board-level review of the standoff voltage, clamping voltage, and AEC-Q101 qualification requirements.","metaTitle":"Vishay 1.5KE15CAHE3/51 TVS Diode, 1500W, 12.8V Standoff","metaDescription":"Obsolete Vishay 1.5KE15CAHE3/51 bidirectional TVS diode, 1500W peak pulse, 12.8V standoff, AEC-Q101.","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":"Bulk","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":"1.5KE15","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"14.3V","Voltage - Clamping (Max) @ Ipp":"21.2V","Voltage - Reverse Standoff (Typ)":"12.8V","Current - Peak Pulse (10/1000µs)":"70.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5346","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55e3e40e24fd2c3f96443c3e231bf459.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I source the 1.5KE15CAHE3/51 now that it is obsolete?","answer":"Because it is obsolete, lot quantities and date codes vary — each RFQ is handled on its own terms."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE15CAHE3-51","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE15CAHE3-51 when reusing this data.
