Reverse standoff is 17 V typical — above this the device is reverse-biased and leaks minimally; once the transient pushes the cathode above 18.9 V the Zener channel avalanches and clamps the voltage at 27.6 V maximum, limiting the surge current the protected load sees. The 27.6 V clamping ceiling is the design constraint — whatever circuit sits behind this TVS sees no more than 27.6 V during the surge event, so downstream ICs and regulators must tolerate that as their abs-max transient input. ## DO-214AB package and board-level fit The SMC (DO-214AB) package is the standard two-diode-length variant — the footprint and pad geometry must match the land pattern for proper solder joint reliability and thermal transfer from the die attach tab to the PCB copper. Surface-mount orientation means the cathode bar on the component matches the strip packaging polarity — for bidirectional protection the orientation is symmetric, but the single-channel designation confirms one clamp path only.","metaTitle":"Diotec 1.5SMCJ17CA TVS Diode, 1500W 27.6V SMC","metaDescription":"Bidirectional TVS diode, 17V standoff, 27.6V clamping, 1.5kW peak pulse in DO-214AB.
