The single bidirectional channel replaces two unidirectional TVS diodes wired in anti-series, saving board area and reducing the parts count. ## Package, footprint and thermal integration Housed in the DO-214AC (SMA) package, the SMAJ8.5CA-13-F uses the standard surface-mount footprint for this power class — the same pad layout as a typical SMB or SMC device with a smaller body. The supplier device package is also designated SMA, so the land pattern matches the industry-standard SMA solder pad geometry. The -55°C to +150°C junction temperature range covers military and industrial thermal environments; the 400W peak pulse rating is derated linearly above 25°C per the datasheet curve, so the effective pulse power at 85°C ambient drops to roughly 280W. The low leakage at standoff voltage (not listed but typical for this Zener family) keeps the quiescent drain negligible on battery-powered lines. The base product number is SMAJ8.5, so other package variants (SMB, SMC) or unidirectional versions in the same family share the same silicon and are parametric drop-ins for different power levels. Available through independent distribution channels; pricing and lead time are confirmed at RFQ against the BOM quantity.","metaTitle":"SMAJ8.5CA-13-F Diodes Inc TVS, 400W, 8.5V Bidirectional, SMA","metaDescription":"SMAJ8.5CA-13-F Diodes Inc bidirectional Zener TVS diode, 400W peak pulse power, 8.5V standoff, 14.4V clamp, DO-214AC SMA package, -55°C to +150°C, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diodes Incorporated","Type":"Zener","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"400W","Base Product Number":"SMAJ8.5","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMA","Voltage - Breakdown (Min)":"9.44V","Voltage - Clamping (Max) @ Ipp":"14.4V","Voltage - Reverse Standoff (Typ)":"8.5V","Current - Peak Pulse (10/1000µs)":"27.7A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0270111b098582f24c0b7d28e81a77ac.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/SMAJ8.5CA-13-F","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diodes-inc/SMAJ8.5CA-13-F when reusing this data.
