The 15.3V reverse standoff voltage (Vrwm) means this part sits across a 12V or 15V rail and stays transparent until the transient exceeds that threshold. Breakdown starts at 17.1V minimum, so a 15V rail with 5% tolerance won't trigger false clamping. ## Pulse power and thermal budget The 1500W rating is for a 10/1000µs exponential waveform at 25°C. Derate above that — the -65°C to 150°C junction temperature range gives headroom for high-ambient enclosures, but the peak pulse power drops linearly above 25°C per the datasheet curve. At 59.5A peak pulse current, the clamping voltage of 25.2V means the instantaneous power during the pulse is about 1500W. That's the energy the die absorbs before the transient decays — the DO-214AB body and solder pads sink the heat between events. No power line protection built in — this is a unidirectional device for signal or low-voltage DC rails, not for AC mains. The single Zener channel clamps positive transients to ground; reverse polarity is handled by the diode's forward conduction. ## Board-fit and procurement posture Surface-mount on a DO-214AB footprint — the SMC package is larger than the SMA/SMB siblings, which helps with solder joint reliability under repeated pulse stress. The Tape & Reel (TR) and Cut Tape (CT) options suit both prototype pick-and-place and production reels. Active lifecycle means this part is still in the manufacturer's standard product line.","metaTitle":"Central Semiconductor 1.5SMC18A TR13 PBFREE TVS, 1500W","metaDescription":"Central Semiconductor 1.5SMC18A TR13 PBFREE Zener TVS diode, 1500W peak pulse power, 15.3V reverse standoff, DO-214AB (SMC), surface mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Central Semiconductor Corp","Type":"Zener","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-65°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMC","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"17.1V","Voltage - Clamping (Max) @ Ipp":"25.2V","Voltage - Reverse Standoff (Typ)":"15.3V","Current - Peak Pulse (10/1000µs)":"59.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9191afc3e92f03eb3c6f3d25e0a397c7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC18A%20TR13%20PBFREE/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/central-semiconductor-corp/1.5SMC18A-TR13-PBFREE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/central-semiconductor-corp/1.5SMC18A-TR13-PBFREE when reusing this data.
