Motorola Bipolar Power Transistor Device Data
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 = l/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.
