The 33 V reverse standoff is the continuous working voltage the line sits at without the TVS conducting — the rail the protected circuit normally sees. Breakdown kicks in at 36.7 V minimum, meaning the device starts conducting and clamping transient energy above that threshold. A faster or higher-energy transient will push the clamping voltage above 53.3 V before the device absorbs the full energy, so the system designer must verify that the clamped voltage stays below the downstream IC absolute-maximum rating at the prospective short-circuit current of the source. ## Wide temperature grade and telecom deployment Telecom applications include protection on DC power bus rails feeding remote radio units and on the secondary side of POEswitches, where the 33 V standoff covers the common 24–48 V telecom power rails. ## Sourcing the 5.0SMDJ33CA Tape & Reel and Cut Tape options are listed — the Cut Tape option is useful for low-volume prototypes or board-rework stock without committing to a full reel.","metaTitle":"Bourns 5.0SMDJ33CA TVS Diode, 33V Standoff, 5kW Peak","metaDescription":"Bourns 5.0SMDJ33CA bidirectional Zener TVS diode, 33V standoff, 36.7V min breakdown, 53.3V clamping, 5kW peak pulse, DO-214AB SMC.
