When a transient drives the line above the 133 V minimum breakdown threshold, the Zener snaps into conduction and clamps the peak at no more than 193 V, protecting downstream components from overvoltage stress. For a motor drive or power-supply input bus, this handles the front-end IEC 61000-4-5 surge test class without cascading upstream. ## Junction thermal margin and board assembly The SMC (DO-214AB) package is a standard reflow-profile part with a solid thermal path through the cathode tab to the PCB pad; verify the land pattern matches the recommended paste mask to avoid tombstoning on fine-pitch rework.","metaTitle":"1.5SMCJ120A_R1_00001 TVS Diode, 120V Standoff, Panjit","metaDescription":"Panjit 1.5SMCJ120A unidirectional TVS Zener, 120V standoff, 133V breakdown, 193V clamping @ 7.9A peak pulse.
