The reverse standoff voltage of 33 V typ sets the continuous working voltage; the part remains inactive during normal operation and activates only on a transient exceedance. ## Temperature and qualification for under-hood deployment At 150°C junction, the Zener leakage current rises above the room-temperature figure, so thermal management matters in tightly packed modules where the TVS shares a heatsink plane with downstream components. ## Sourcing posture for BOM entry Bourns lists the 5.0SMDJ33A-QH as Active. For new automotive designs the part is a valid BOM entry; the tape-and-reel packaging suits standard SMT assembly lines.","metaTitle":"Bourns 5.0SMDJ33A-QH Zener TVS 33V 5kW DO-214AB","metaDescription":"Bourns 5.0SMDJ33A-QH Zener TVS diode, AEC-Q101 automotive, 33V standoff, 53.3V clamping, 5kW peak pulse, DO-214AB SMC surface mount.

Bourns lists it as Active, and the tape-and-reel packaging is standard SMT. Confirm reel split and lead time at RFQ — quantities, pricing, and stock position are verified at quote time, not stated here."},{"question":"What series is the 5.0SMDJ33A-QH and what does AEC-Q101 mean for my automotive build?","answer":"It belongs to the 5.0SMDJ-Q series and carries AEC-Q101 qualification. That certification means Bourns tested this TVS to the automotive stress-grade sequence — temperature cycling, humidity bias, and surge life — before releasing it for automotive ECU designs. The junction temperature ceiling of 150°C matches the under-hood operating band, so the part is qualified for engine-compartment and body-control module applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/bourns-inc/5.0SMDJ33A-QH","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/bourns-inc/5.0SMDJ33A-QH when reusing this data.
