The single bidirectional channel handles both positive and negative transients, simplifying the BOM for a 12 V automotive bus where reverse-battery and load-dump events can swing either polarity. ## Obsolete — sourcing reality for sustainment programs Vishay has marked the 1.5KE12CHE3/73 as obsolete. The DO-201AA axial-lead package (also known as DO-27) is a standard through-hole footprint shared across the 1.5KE family. A pin-compatible functional replacement from the same family may exist, but no direct cross-reference is recorded in the manufacturer's lifecycle documentation.","metaTitle":"1.5KE12CHE3/73 Vishay TVS, 1500W, 9.72V, Obsolete","metaDescription":"Vishay 1.5KE12CHE3/73 automotive TVS diode, 1500W peak pulse, 9.72V 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":"Tape & Box (TB)","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":"1.5KE12","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"10.8V","Voltage - Clamping (Max) @ Ipp":"17.3V","Voltage - Reverse Standoff (Typ)":"9.72V","Current - Peak Pulse (10/1000µs)":"86.7A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What automotive qualification does this TVS carry?","answer":"AEC-Q101 qualified, which covers the stress and reliability testing required for automotive-grade discrete semiconductors.
