DTA144VKA Datasheet PNP -100mA -50V Digital Transistors (Bias Resistor Built-in Transistors) l Outline Parameter VCC Value IC(MAX.) -100mA R1 47k 10k or -50V e N co ew m m D es en ig de ns d f R2 SMT3 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 R l Application Switching circuit, Inverter circuit, Interface circuit, ot Driver circuit N l Packaging specifications Part No. DTA144VKA Package Package size Taping code SMT3 2928 T146 www.rohm.com (c) 2012 ROHM Co., Ltd.
