Budget your TVS accordingly: a longer or higher-energy pulse eats into the peak-pulse rating faster than the raw wattage number suggests. The junction-temperature limit is the hard stop; the PCB pad geometry and copper area under the SMC body set whether you stay within it at your application's peak ambient. ## DO-214AB footprint and the BOM position Surface-mount SMC (DO-214AB) is the industry-standard two-terminal package for this power class — the cathode bar marks polarity on the reel. Polarity matters on a unidirectional: anode goes to the protected rail, cathode to the rail side you are clamping toward ground. Tin-lead finish is typical for this series; check the reel labeling if your assembly spec demands a specific plating. Single unidirectional channel — this part protects one power rail or signal line from positive-going transients. If you need bidirectional protection across a bipolar or AC-coupled node, the same SMCJ series offers a bidirectional variant; the standoff and breakdown specs double accordingly. Panjit International Inc. lists this part as Active — it is not in obsolescence, last-time-buy, or NRND status. The 1.5SMCJ series is a general-purpose TVS family; the 22V standoff rating sits in the middle of the series range, so there is a natural parametric ladder above and below it in the same SMC package footprint if your voltage requirement shifts.","metaTitle":"1.5SMCJ22A_R1_00001 TVS Diode, 22V Standoff, DO-214AB","metaDescription":"Panjit 1.5SMCJ22A_R1_00001 unidirectional TVS diode, 22V standoff, 1500W peak pulse, DO-214AB SMC package.
