DTC623TU / DTC623TK
Transistors
Digital transistors (built-in resistor)
DTC623TU / DTC623TK
Features
In addition to the features of regular digital transistors.
1) Low saturation voltage, typically
V
CE (sat)
=40mV at I
C
/ I
B
=50mA / 2.5mA, makes these
transistors ideal for muting circuits.
2) These transistors can be used at high current levels,
I
C
=600mA.
