The 33V reverse standoff voltage means the diode does not conduct at the nominal rail voltage, only above the breakdown threshold. Peak pulse current is 11.3A under the 10/1000 µs test condition. Housed in the DO-214AA (SMB) surface-mount package, the device operates over -65°C to 150°C junction temperature. The SMB footprint is common across many TVS families, easing layout reuse. For BOM planning, this part carries no near-term obsolescence risk.","metaTitle":"SMBJ33AE3/TR13 – Microchip 33V Zener TVS Diode, 600W","metaDescription":"SMBJ33AE3/TR13 Zener TVS diode from Microchip Technology. 33V reverse standoff, 53.3V clamping, 600W peak pulse, DO-214AA SMB.

The '' suffix typically indicates lead-free / RoHS-compliant finish. The 'TR13' suffix denotes Tape & Reel packaging. The electrical ratings (33V standoff, 36.7V breakdown, 53.3V clamping) are identical across the SMBJ33 family variants; confirm the specific suffix with the datasheet for environmental compliance."},{"question":"What is the closest pin-compatible alternative to SMBJ33AE3/TR13?","answer":"Any unidirectional TVS in the DO-214AA (SMB) package with a 33V reverse standoff and similar breakdown/clamping window is a functional cross. The SMBJ33A (without suffix) from Microchip is electrically identical but may differ in lead finish. Other manufacturers' SMBJ33A-family parts in the same package are footprint-compatible; verify the clamping voltage and peak pulse current match your surge requirement."},{"question":"Is SMBJ33AE3 bidirectional or unidirectional?","answer":"It is a unidirectional Zener TVS, with one channel. For bidirectional protection on AC or bipolar rails, use the SMBJ33CA family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMBJ33AE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMBJ33AE3-TR13 when reusing this data.
