Part Description: High voltage fast-switching NPN power transistor

Part Details:

® BUL1203EFP HIGH VOLTAGE FAST-SWITCHING NPN POWER TRANSISTOR s HIGH VOLTAGE CAPABILITY s LOW SPREAD OF DYNAMIC PARAMETERS s MINIMUM LOT-TO-LOT SPREAD FORRELIABLE OPERATION s VERY HIGH SWITCHING SPEED s FULLY INSULATED PACKAGE (U.L.COMPLIANT) FOR EASY MOUNTING APPLICATIONS 3 2 s ELECTRONIC BALLASTS FOR 1 FLUORESCENT LIGHTING (277 V HALFBRIDGE AND 120 V PUSH-PULLTOPOLOGIES) TO-220FP DESCRIPTION The BUL1203EFP is a new device manufacturedusing Diffused Collector technology to enhanceswitching speeds and tight hFE range whilemaintaining a wide RBSOA. INTERNAL SCHEMATIC DIAGRAM Thanks to his structure it has an intrinsicruggedness which enables the transistor towithstand a high collector current level duringBreakdown condition, without using the transilprotection usually necessary in typical convertersfor lamp ballast. ABSOLUTE MAXIMUM RATINGS Symbol Parameter Value Unit VCBO Collector-BaseVoltage (IE = 0) 1200 V VCES Collector-Emitter Voltage (VBE = 0) 1200 V VCEO Collector-Emitter Voltage (IB = 0) 550 V VEBO Emitter-Base Voltage (IC = 0) 9 V IC Collector Current 5 A ICM Collector Peak Current (tp < 5 ms) 8 A IB
