SWITCHMODE Series NPN Silicon Power Darlington Transistor With Base-emitter Speedup Diode

Motorola => Freescale 

SWITCHING TIMES NOTE (continued)

For the designer, there is minimal switching loss during

storage time and the predominant switching power losses

occur during the crossover interval and can be obtained us-

ing the standard equation from AN–222.

PSWT = 1/2 VCC IC (tc) f

] In general, trv + tfi tc. However, at lower test currents this

relationship may not be valid.

As is common with most switching transistors, resistive

switching is specified at 25_C and has become a benchmark

for designers. However, for designers of high frequency con-

verter circuits, the user oriented specifications which make

this a “SWITCHMODE” transistor are the inductive switching

speeds (tc and tsv) which are guaranteed at 100_C.
