® BUF405A BUF405AFP HIGH VOLTAGE FAST-SWITCHING NPN POWER TRANSISTORS s s s s s s HIGH SWITCHING SPEED NPN POWER TRANSISTORS EASY TO DRIVE HIGH VOLTAGE FOR OFF-LINE APPLICATIONS 100 KHz SWITCHING SPEED LOW COST DRIVE CIRCUITS LOW DYNAMIC SATURATION 3 3 1 2 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. 1 2 TO-220 TO-220FP INTERNAL SCHEMATIC DIAGRAM ABSOLUTE MAXIMUM RATINGS Symb ol V CEV V CEO VEBO IC I CM IB I BM P tot T s tg Tj Parameter BUF405A Collector-Emitter Voltage (V BE = -1.5 V) Collector-Emitter Voltage (I B = 0) Emitter-Base Voltage (I C = 0) Collector Current Collector Peak Current (tp < 5 ms) Base Current Base Peak Current (tp < 5 ms) o T otal Dissipation at T c = 25 C Storage Temperature Max O peration Junction T emperature 1000 450 7 7.5 15 3 4.5 80 -65 to 150 150 39 Valu e BUF405AF P V V V A A A A W o C o C Un it January 1999 1/6 BUF405A / BUF405AFP THERMAL DATA T O-220 R t hj-ca se Thermal Resistance Junction-Case Max 1.56 TO-220F P 3.2 o C/W ELECT...
