No successor has been announced — the part is still the primary offering for this 30V standoff, 600W pulse rating. ## 600W peak pulse — clamping at 53.5V Rated for 600W peak pulse power with a 10/1000µs waveform, the SMBJ30E3/TR13 clamps at 53.5V max while conducting 11.2A peak pulse current. The 33.3V minimum breakdown gives a 3.3V guard band above the 30V standoff — enough margin to avoid nuisance triggering on a clean 24V rail but still protect against transients that exceed the rail. ## DO-214AA SMB — surface-mount fit Housed in the DO-214AA (SMB) package, the SMBJ30E3/TR13 is a surface-mount Zener TVS. The SMB footprint is smaller than the SMC but larger than the SMA — it suits boards where the 600W pulse rating demands a bigger junction than an SMA can dissipate, but the layout cannot fit an SMC.","metaTitle":"SMBJ30E3/TR13 – Microchip 600W Zener TVS, DO-214AA, Active","metaDescription":"Microchip SMBJ30E3/TR13 Zener TVS diode, 600W peak pulse, 30V standoff, DO-214AA SMB.

The SMBJ30A may have a different plating or be from a different manufacturer. Check the specific datasheet for the SMBJ30A to confirm package and electrical specs — the clamping voltage and pulse power should be identical, but the plating and qualification level can differ."},{"question":"Is the SMBJ30E3/TR13 unidirectional?","answer":"Yes, it is a single unidirectional channel, meaning it protects one rail against positive transients referenced to ground. For bidirectional protection on AC lines or bipolar rails, you would need two devices back-to-back or a bidirectional TVS."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMBJ30E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMBJ30E3-TR13 when reusing this data.
