Available through independent surplus and excess inventory channels. Quantities are lot-specific; traceability and date codes are confirmed at RFQ. No pin-compatible direct replacement exists from Vishay — a parametric search for a 1500 W, 12.9 V standoff TVS in DO-201AA is the alternative path for a board spin. ## Package and temperature envelope DO-201AA (DO-27) axial-lead through-hole package — the leads are crimped into the board and the body stands off the PCB. The junction temperature range spans -55°C to 175°C, covering the full automotive ambient plus the self-heating margin from the pulse current. Single bidirectional channel — one device clamps both polarities, saving a diode count on the rail compared to back-to-back unidirectional parts.","metaTitle":"Vishay 1.5KE16CHE3/73 TVS, 1500W, 12.9V Standoff","metaDescription":"Obsolete Vishay 1.5KE16CHE3/73 automotive TVS diode, AEC-Q101, 1500W peak pulse, 12.9V standoff.","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":"1.5KE16","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"14.4V","Voltage - Clamping (Max) @ Ipp":"23.5V","Voltage - Reverse Standoff (Typ)":"12.9V","Current - Peak Pulse (10/1000µs)":"63.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How do I get current pricing and availability for 1.5KE16CHE3/73?","answer":"Submit an RFQ through this listing.
