DTD123YK NPN 500mA 50V Digital Transistors (Bias Resistor Built-in Transistors) Datasheet lOutline Parameter Value SMT3 OUT V 50V CC I 500mA IN C(MAX.) GND R 2.2kW 1 DTD123YK R 10kW 2 SOT-346 (SC-59) lFeatures 1) Built-In Biasing Resistors lInner circuit 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 :DTB123YK 6) Lead Free/RoHS Compliant. lApplication Switching circuit, Inverter circuit, Interface circuit, Driver circuit lPackaging specifications Package Basic Taping Reel size Tape width Part No. Package size ordering Marking code (mm) (mm) (mm) unit (pcs) DTD123YK SMT3 2928 T146 180 8 3,000 F62 www.rohm.com © 2012 ROHM Co., Ltd.
