Robust, high-temperature SCRs for industrial applications
1200 V SCRs in TO247HC: creepage engineered for high-voltage compliance
1200 V SCRs in TO247HC: creepage engineered for high-voltage compliance
ST's 1200 V SCR portfolio in TO247HC packaging addresses creepage and clearance compliance in high-voltage industrial power without potting or lead forming. The package geometry - 6.7 mm creepage distance and 17 mm lead length - enables direct IEC 60664-1 compliance for systems up to 470 Vrms in Pollution Degree 2 environments. Available in 50 A, 80 A, and 130 A ratings for soft starters, controlled rectifiers, and solid-state relays.
