JEDEC TO-220AB These devices are designed to switch from an off-state to an on-state for either polarity of applied voltage with positive or negative gate triggering voltages. They have an on-state current rating of 6-A at T, = 75C (SC141 series) and 10-A at Te = 80 (SC146 series) and repetitive off-state voltage ratings, of 200, 400, 500, 600, and 800 valts. All devices utilize the JEDEC TO-220AB (VERSAWATT) plastic package.
