The 600W rating is the energy-handling ceiling; the actual margin depends on the application's surge impedance and repetition rate. ## Breakdown and standoff — where the protection triggers The reverse standoff voltage is 20V, meaning the diode remains non-conductive below this level. Breakdown occurs at a minimum of 22.2V, so the device starts clamping between 22.2V and the 32.4V maximum clamp. This window defines the trip point for a 20V rail — the diode does not load the line during normal operation. Power line protection is not featured, confirming this is a signal or low-power rail protector, not a mains-side suppressor. ## Package and temperature range for the board The base product number is SMBJ20; the suffix indicates the lead-free / RoHS-compliant finish. This status supports new designs and long-term BOM commitments without a forced migration window.","metaTitle":"SMBJ20AE3/TR13 TVS Diode – 20V Standoff, 32.4V Clamp, 600W","metaDescription":"Microchip SMBJ20AE3/TR13 Zener TVS: 20V reverse standoff, 32.4V max clamp at 18.5A, 600W peak pulse, DO-214AA SMB.","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-214AA, SMB","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"SMBJ20","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMBJ (DO-214AA)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"22.2V","Voltage - Clamping (Max) @ Ipp":"32.4V","Voltage - Reverse Standoff (Typ)":"20V","Current - Peak Pulse (10/1000µs)":"18.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2850","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f566c62ad8bf6be9ecf452f6999d0b7a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SMBJ20AE3/TR13 a direct replacement for SMBJ20A?","answer":"The SMBJ20A (without) is the same die in the same package but with a tin-lead finish.
