It is a Zener-type device that responds to overvoltage events by shunting surge current to ground, protecting downstream semiconductors. Maximum clamping voltage at the peak pulse current of 93A (8/20µs waveform) is 42.8V, which defines the voltage the protected circuit sees during a surge. The DO-214AA (SMB) surface-mount package suits automated assembly for industrial control, telecom infrastructure, and power supply applications where board space is a constraint. For a 20.5V rail, this provides substantial margin against typical industrial surges from inductive load switching or lightning-induced transients on external cables. The 93A peak pulse current at the 8/20µs waveform is the more relevant number for ESD and fast transient protection, as it reflects the diode's ability to handle high-current, short-duration events. For BOM planning, this removes the obsolescence risk that drives urgent redesigns. No direct replacement or second-source alternate is recorded in the official cross-reference data, so the SM6T24A is the sole TRANSIL™ option at this voltage and power level in the DO-214AA package.","metaTitle":"SM6T24A STMicroelectronics TVS Diode, 600W, 20.5V Standoff","metaDescription":"SM6T24A from STMicroelectronics is a 600W unidirectional TVS diode in DO-214AA (SMB) package. 22.8V breakdown, 42.8V clamping, 93A peak pulse current.","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":"SM6T24","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMB (DO-214AA)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"22.8V","Voltage - Clamping (Max) @ Ipp":"42.8V","Voltage - Reverse Standoff (Typ)":"20.5V","Current - Peak Pulse (10/1000µs)":"93A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1e6a6ede6221d6b6009e7d617f0a0cd9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SM6T24A/alternatives.json"},"ai":{"faq":[{"question":"Is SM6T24A a direct replacement for SM6T24?","answer":"The SM6T24A is the standard suffix variant of the base SM6T24 product number. The 'A' typically indicates a tighter tolerance on breakdown voltage, but the official record does not list a direct-replacement relationship between the two. Verify the specific breakdown tolerance required for your design before substituting."},{"question":"Is SM6T24A a bidirectional TVS diode?","answer":"No, the SM6T24A is a unidirectional TVS diode, with one channel for clamping transients in one polarity.
