DTD123TK NPN 500mA 40V Digital Transistors Datasheet (Bias Resistor Built-in Transistors) lOutline Parameter Value VCEO IC R 40V 500mA 2.2kW SMT3 Collector Base Emitter DTD123TK SOT-346 (SC-59) lFeatures lInner circuit 1) Built-In Biasing Resistors 2) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see inner circuit). 3) The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of completely eliminating parasitic effects. 4) Only the on/off conditions need to be set for operation, making the circuit design easy. 5) Complementary PNP Types :DTB123TK 6) Lead Free/RoHS Compliant. lApplication Switching circuit, Inverter circuit, Interface circuit, Driver circuit lPackaging specifications Part No. DTD123TK Package Package size (mm) Taping code SMT3 2928 T146 www.rohm.com © 2012 ROHM Co., Ltd.
