Digital transistors (built-in resistor)
DTC643TU / DTC643TK
!Features In addition to the features of regular digital transistors. 1) Low saturation voltage, typically VCE (sat) =40mV at IC / IB=50mA / 2.5mA, makes these transistors ideal for muting circuits. 2) These transistors can be used at high current levels, IC=600mA. !External dimensions (Unit : mm)
