Breakdown triggers at a minimum of 114V, with the avalanche clamping the transient to 165V maximum at the rated 9.1A peak pulse current. The single bidirectional channel means the same device protects both polarities, which simplifies BOM consolidation on AC-coupled signal lines or bipolar power rails where the transient can swing either direction. Operating junction temperature spans -65°C to 150°C, so the diode maintains its clamping characteristic across the full automotive-grade thermal envelope without derating the peak pulse power at cold start or underhood soak-back. The DO-214AB (SMC) package footprint matches the industry-standard SMCJ land pattern, making it a drop-in replacement for other 1500W bidirectional TVS devices in the same case size.","metaTitle":"Vishay 1.5SMC120CA-M3/57T Bidirectional TVS, 1500W","metaDescription":"Vishay 1.5SMC120CA-M3/57T Zener TVS diode, 1500W peak pulse power, 102V standoff, 165V clamping, DO-214AB.
