It clamps transients on a nominal 85.5 V rail, with a minimum breakdown voltage of 95 V and a maximum clamping voltage of 178 V at 22.5 A peak pulse current. The single bidirectional channel means you don't have to worry about polarity — it protects AC-coupled or bipolar signal lines just as well as DC power rails. The DO-214AA (SMB) surface-mount package fits standard reflow processes and saves board space compared to axial-leaded alternatives. ## Breakdown and clamping — where the protection window sits With a reverse standoff voltage of 85.5 V, the SM6T100CA stays out of the way during normal operation on a 72 V or 80 V bus. The 95 V minimum breakdown gives a guard band before the device starts conducting. The 178 V maximum clamping voltage is the ceiling the load sees during a surge — make sure your downstream components can survive that peak. The 22.5 A peak pulse current rating (8/20 µs waveform) tells you how much surge it can sink before the junction gives up. ## Temperature range and environment The 150°C upper limit gives headroom for self-heating during repetitive surge events, though derating applies above 25°C — the 600 W rating is for 25°C ambient, so at 85°C you lose about half that capability. Plan your thermal margin accordingly if the part sits near a hot regulator or in a sealed enclosure.","metaTitle":"STMicroelectronics SM6T100CA TVS Diode, 600W Bidirectional","metaDescription":"STMicroelectronics SM6T100CA bidirectional TVS diode, 600W peak pulse power, 95V min breakdown, 85.5V standoff, DO-214AA SMB.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"SM6T, TRANSIL™","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AA, SMB","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"SM6T100","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMB (DO-214AA)","Voltage - Breakdown (Min)":"95V","Voltage - Clamping (Max) @ Ipp":"178V","Voltage - Reverse Standoff (Typ)":"85.5V","Current - Peak Pulse (10/1000µs)":"22.5A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1e6a6ede6221d6b6009e7d617f0a0cd9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SM6T100CA bidirectional or unidirectional?","answer":"SM6T100CA is a single bidirectional channel device.
