1 / 6 page BUF405A BUF405AFP HIGH VOLTAGE FAST-SWITCHING NPN POWER TRANSISTORS s HIGH SWITCHING SPEED NPN POWER TRANSISTORS s EASY TO DRIVE s HIGH VOLTAGE FOR OFF-LINE APPLICATIONS s 100 KHz SWITCHING SPEED s LOW COST DRIVE CIRCUITS s LOW DYNAMIC SATURATION APPLICATIONS: s SWITCH MODE POWER SUPPLIES s MOTOR DRIVERS DESCRIPTION These Easy-to-Drive FASTSWITCH NPN power transistors are specially designed for high reliability industrial and professional power driving applications such us motor drives and off-line switching power supplies. ETD transistors will operate using easy drive circuits at up to 100KHz; this helps to simplify designs and improve reliability. The superior switching performance and low crossover losses reduce dissipation and consequently lowers the equipment operating temperature. ® INTERNAL SCHEMATIC DIAGRAM January 1999 ABSOLUTE MAXIMUM RATINGS Symb ol Parameter Valu e Un it BUF405A BUF405AF P VCEV Collector-Emitter Voltage (VBE = -1. 5 V) 1000 V VCEO Collector-Emitter Voltage (IB = 0) 450 V VEBO Emitter-Base Voltage (IC =0) 7 V IC Collector Current 7. 5 A ICM Collector Peak Current (tp <5 ms) 15 A IB Base Current 3 A IBM Base Peak Current (tp <5 ms) 4. 5 A Ptot T otal Dissipat ion at Tc =25 oC80 39 W Tstg Storage Temperature -65 to 150 oC Tj Max O peration Junction T emperat ure 150 oC 1 2 3 TO-220 TO-220FP 1 2 3 1/6 |
