DTA144VKA Datasheet PNP -100mA -50V Digital Transistors (Bias Resistor Built-in Transistors) l Outline Parameter VCC Value IC(MAX.) -100mA R1 47kΩ 10kΩ SMT3 -50V R2 SOT-346(SC-59) l Features 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 NPN Type: DTC144VKA 6) Lead Free/RoHS Compliant. l Inner circuit l Application Switching circuit, Inverter circuit, Interface circuit, Driver circuit l Packaging specifications Part No. DTA144VKA Package Package size Taping code SMT3 2928 T146 Reel size Tape width (mm) (mm) 180 8 Basic ordering unit.(pcs) Marking 3000 E56 www.rohm.com © 2012 ROHM Co., Ltd.
