BTA10 GP TRIACS FEATURES .LOW IH = 13mA max .HIGH SURGE CURRENT : ITSM = 120A .IGT SPECIFIED IN FOUR QUADRANTS .INSULATING VOLTAGE = 2500V(RMS) (UL RECOGNIZED : E81734) A1 DESCRIPTION A2 G The BTA10 GP’s use high performance, glass pas- sivated chips. TO220AB The insulated TO220AB package, the high surge (Plastic) current and low holding current make this family well adapted to LIGHT DIMMER applications.
