The 30V reverse standoff voltage (working voltage) means the diode will not conduct at normal 30V DC operation. Breakdown starts at a minimum of 33.3V, and clamping is guaranteed at 48.4V max with a 12.4A peak pulse — so a 48V transient on the rail gets clipped to that level. The 600W peak pulse power is the energy-handling ceiling; if your transient exceeds that, you need a higher-power part or a series resistor to limit current. ## Package and temperature range — board fit and environment Housed in the DO-214AA (SMB) surface-mount package, the footprint is standard and widely supported by pick-and-place equipment.","metaTitle":"SMBJ30CAE3/TR13 – Microchip 600W Bidirectional TVS Diode","metaDescription":"Active-production Zener TVS diode from Microchip. 600W peak pulse, 30V reverse standoff, bidirectional, DO-214AA SMB package.

The diode will not load the line at 30V DC, and it clamps transients to 48.4V max. Confirm your transient energy stays under the 600W peak pulse rating."},{"question":"Can I use SMBJ30CAE3/TR13 as a replacement for SMBJ30A?","answer":"The SMBJ30A is a unidirectional version; the SMBJ30CAE3/TR13 is bidirectional. Pin-compatible in the same DO-214AA footprint, but the bidirectional variant clamps both polarities. If your circuit expects a single-direction clamp, verify the bidirectional characteristic does not affect your design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMBJ30CAE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMBJ30CAE3-TR13 when reusing this data.
