Breakdown occurs at 114 V minimum, and clamping is specified at 165 V maximum at the rated 9.1 A peak pulse current. That 165 V clamp ceiling is the key number for the downstream components: any device rated for 200 V or more on that rail has 35 V of headroom above the clamp. If the protected circuitry uses 150 V-rated FETs or capacitors, the margin tightens — a 165 V clamp leaves only 15 V before the part's abs-max is reached, which may be acceptable for a single-event transient but not for repetitive pulsing. Bidirectional operation (one channel) means the diode clamps symmetrically on both polarities — useful for AC signal lines or bipolar DC rails where the transient can swing positive or negative relative to ground. Operating temperature spans -65°C to +150°C junction, which covers military and industrial ambient ranges without derating the surge capability at the high end.","metaTitle":"Vishay 1.5SMC120CA-E3/9AT TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5SMC120CA-E3/9AT bidirectional Zener TVS, 1500W peak pulse power, 102V standoff, DO-214AB.
