The 328V clamping ceiling means a 24V or 48V automotive bus with 185V-rated downstream components sees the transient clipped before dielectric breakdown. The single bidirectional channel handles both positive and negative surges on one line, saving a diode and PCB space compared to two unidirectional devices in anti-series. The 1500W peak pulse rating at 10/1000µs covers the typical automotive load-dump pulse per ISO 7637-2 pulse 5a/5b. ## Through-hole DO-201 package and thermal range Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE220CAHB0G mounts through-hole — the lead frame conducts surge current directly into the PCB copper pour, which acts as the heatsink. Bulk packaging means the parts ship in tubes or trays, not tape-and-reel — typical for through-hole TVS diodes ordered for manual or wave-solder assembly. ## Active production and sourcing posture The AEC-Q101 documentation and RoHS compliance data are provided with the shipment.","metaTitle":"TSC 1.5KE220CAHB0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE220CAHB0G bidirectional TVS diode, 1500W peak pulse power, 328V clamping, AEC-Q101 automotive grade, DO-201 axial package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Grade":"Automotive","Series":"1.5KE","Package":"Bulk","Applications":"-","Mounting Type":"Through Hole","Qualification":"AEC-Q101","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE220","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"209V","Voltage - Clamping (Max) @ Ipp":"328V","Voltage - Reverse Standoff (Typ)":"185V","Current - Peak Pulse (10/1000µs)":"4.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3688","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 1.5KE220CAHB0G and check availability?","answer":"The 1.5KE220CAHB0G is an active-production part from Taiwan Semiconductor Corporation.
