Unidirectional only — it protects one polarity, which is what you need for positive-going transients on a DC rail. Power-line protection is not rated for this device, so it sits in the general-purpose category rather than the mains-protection subclass — do not spec it as a primary AC line protector.","metaTitle":"Diotec 1.5SMCJ90A Zener TVS, 1500W Peak Pulse","metaDescription":"Diotec 1.5SMCJ90A unidirectional Zener TVS diode, 90V standoff, 100V min breakdown, 146V clamping at 10.3A peak.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diotec Semiconductor","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","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":"-50°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"100V","Voltage - Clamping (Max) @ Ipp":"146V","Voltage - Reverse Standoff (Typ)":"90V","Current - Peak Pulse (10/1000µs)":"10.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8704","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/01145f0f8259fe3e96a1c23446f6a0b9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ90A/alternatives.json"},"ai":{"faq":[{"question":"What family members share the same DO-214AB footprint as 1.5SMCJ90A?","answer":"The 1.5SMCJ series covers a wide range of standoff voltages in the same SMC package — any unidirectional sibling with the same pinout and a standoff voltage in the range of your rail is a candidate.
