The reverse standoff voltage is 9.4 V typical — the signal or power rail should stay below this during normal operation to avoid leakage. Breakdown occurs at a minimum of 10.5 V, and the clamping voltage at peak pulse current is 15.6 V maximum. With a peak pulse current rating of 96.2 A (10/1000 µs), the diode can absorb a 1.5 kW surge before the clamping voltage is reached. The operating temperature range spans -55°C to +175°C, covering the full automotive under-hood ambient plus margin for self-heating during a surge event. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE11CAHE3/51 is designed for point-to-point wiring or PCB mounting with through-hole pads. The axial leads suit high-reliability connections in vibration-prone environments like engine bays.","metaTitle":"1.5KE11CAHE3/51 Vishay TVS Diode, 1500W, Bidirectional","metaDescription":"Obsolete Vishay 1.5KE11CAHE3/51 bidirectional TVS diode, 1500W peak pulse, 9.4V 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":"1.5KE11","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"10.5V","Voltage - Clamping (Max) @ Ipp":"15.6V","Voltage - Reverse Standoff (Typ)":"9.4V","Current - Peak Pulse (10/1000µs)":"96.2A"}},"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":"What is the closest pin-compatible alternative to 1.5KE11CAHE3/51?","answer":"A functionally equivalent bidirectional TVS in the same DO-201AA package with a 9.4 V standoff and 1500 W rating would need to be selected from current Vishay or competitor families, but pin compatibility is not guaranteed without a board spin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE11CAHE3-51","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/1.5KE11CAHE3-51 when reusing this data.
