That 500W peak pulse rating in the DO-214AC (SMA) package handles common surge events like inductive kickback or lightning-coupled transients in industrial and automotive environments. ## Peak pulse power and clamping behaviour Rated at 500W peak pulse power per the 10/1000µs waveform, this part absorbs a 9.3A surge before the clamp voltage reaches 53.5V. The 33.3V minimum breakdown ensures the TVS does not conduct during normal 24V operation, only during overvoltage events. ## Active lifecycle and ordering code The base product number is SMAJ30; the /TR13 variant is the lead-free, tape-and-reel version. ## Temperature grade and mounting Surface-mount DO-214AC (SMA) is a standard footprint; the solder pad area under the cathode tab sets the thermal resistance. No special bake-out required for MSL 1-rated parts, but confirm the reel date code if the part has been stored beyond the floor-life label.","metaTitle":"SMAJ30E3/TR13 – Microchip 30V Zener TVS, DO-214AC, 500W","metaDescription":"SMAJ30E3/TR13 from Microchip Technology: Zener TVS diode, 30V reverse standoff, 500W peak pulse, DO-214AC (SMA), active lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"SMAJ30","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AC (SMA)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"33.3V","Voltage - Clamping (Max) @ Ipp":"53.5V","Voltage - Reverse Standoff (Typ)":"30V","Current - Peak Pulse (10/1000µs)":"9.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7b3ddece4863b4621debe180df56adc8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can SMAJ30E3/TR13 protect a 24V DC rail?","answer":"Yes. The 30V reverse standoff provides 6V of headroom above a 24V nominal rail, so the TVS does not conduct during normal operation. The 33.3V minimum breakdown triggers only during overvoltage events, clamping at 53.5V maximum. This is a common choice for 24V industrial sensor or PLC power inputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ30E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ30E3-TR13 when reusing this data.
