DTC343TK / DTC343TS Transistors Digital transistors (built-in resistor) DTC343TK / DTC343TS zCircuit schematic zFeatures In addition to the features of regular digital transistors, 1) Low VCE(sat) makes these transistors ideal for muting circuits. (Typ. 0.04V at IC/IB=50/2.5mA) 2) They can be used at high current.
