The DO-214AB (SMC) package keeps the thermal path to the board copper — the junction-to-ambient resistance drops as the pad area increases. Microchip lists this part as Active. The base product number SMCJ33 covers a family of unidirectional and bidirectional variants, but the CE3 suffix identifies this specific bidirectional Zener die in a Tape & Reel (TR) package. Operating temperature range -65°C to 150°C (TJ) covers military and industrial extremes — the junction rating is the same as the case rating, no derating needed for ambient up to 125°C as long as the board copper is adequate. ## Sourcing and availability reality No stock-holding claim here — we source per RFQ across multiple distributor channels. The DO-214AB footprint is shared across the SMCJ series, so board layout is standard. Bidirectional channel means the device clamps both polarities — no orientation sensitivity during assembly.","metaTitle":"SMCJ33CE3/TR13 Microchip 33V Zener TVS Diode, DO-214AB","metaDescription":"SMCJ33CE3/TR13 Microchip Zener TVS, 33V reverse standoff, 59V clamp, 1500W peak pulse.

The device clamps voltage spikes of either polarity symmetrically, with a single junction for both directions. No need to orient the part on the board."},{"question":"What is the closest pin-compatible alternative to SMCJ33CE3/TR13?","answer":"Within the SMCJ33 family, the unidirectional version (SMCJ33A) shares the same DO-214AB footprint and electrical ratings except it clamps only one polarity. For bidirectional, the SMCJ33CA is the standard commercial-grade sibling — same die, same package, but without the CE3 military-temp rating. Verify the operating temperature range and AEC-Q grade if your application requires them."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMCJ33CE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMCJ33CE3-TR13 when reusing this data.
