Automotive, AEC-Q101, 5.0SMDJ-Q Zener TVS diode, 33V reverse standoff, 53.3V clamping, 93.9A peak pulse, 5000W, bidirectional, -55°C to 150°C, DO-214AB SMC surface mount, Tape & Reel.","salesMarkdown":"The 5.0SMDJ33CA-QH is a bidirectional TVS (Transient Voltage Suppressor) diode in the SMC (DO-214AB) package — Bourns classifies the type as Zener in the product record. The standoff voltage of 33 V defines the normal working rail it protects; anything above that is a clamping event. The 5 kW peak pulse rating is the device's ability to swallow a short-duration energy spike without going into thermal runaway; it does not describe continuous dissipation. ## AEC-Q101 qualification and the under-hood temperature envelope The junction temperature rating of -55°C to 150°C spans the cold-crank startup case and the sustained elevated temperatures seen at the ECU or power-distribution node under full load. The automotive series designation puts this part in the Bourns 5.0SMDJ-Q product line, purpose-built for load-dump and inductive kickback protection in 12 V and 24 V vehicle electrical systems. ## SMC package and tape-and-reel assembly integration The DO-214AB (SMC) body is the mid-power TVS footprint — larger than the SMA (DO-214AC) used for sub-1 kW parts and smaller than the SMB (DO-214AA). The cathode band marks the polarity orientation on the bidirectional device; confirm the band aligns with the schematic polarity convention before reflow. The tape-and-reel packaging is standard for high-volume SMT line feeding; reel diameter and leader/trailer length follow the IEC 60286-2 reel standard — your pick-and-place feeder must be sized for the 13-inch reel if that is the standard reel format. Surface-mount termination is matte-tin or equivalent per the series process spec; the board pad footprint is the standard SMC land pattern from IPC-7351.","metaTitle":"Bourns 5.0SMDJ33CA-QH TVS Diode, 33V standoff","metaDescription":"Bourns 5.0SMDJ33CA-QH bidirectional TVS diode, 33V standoff, 53.3V clamping at 93.9A peak, AEC-Q101 automotive, DO-214AB SMC surface mount.
