With a bidirectional channel configuration a single SMC device handles both polarities of surge — useful on data lines and rails where the transient can swing either direction without needing two diodes. ## Selection window: standoff, breakdown, and clamping The 33 V reverse standoff is the working rail the TVS sees in normal operation — it sits below the breakdown threshold so it draws only microamps and does not affect the circuit at nominal voltage. Breakdown triggers at 36.7 V minimum; this is the inflection point where the Zener characteristic steepens and the diode begins conducting, clamping the overvoltage before it propagates downstream. ## Package, mounting, and sourcing posture The SMC/DO-214AB package is the standard JEDEC DO-214AB surface-mount outline — compatible with standard reflow and IR solder profiles and mates to the same pad geometry across multiple manufacturers.","metaTitle":"Diotec 1.5SMCJ33C TVS Diode, 33V Standoff, SMC","metaDescription":"Diotec 1.5SMCJ33C Zener TVS diode, 33V reverse standoff, 59V clamping, 1500W peak pulse.
