DTA144VKA Datasheet PNP -100mA -50V Digital Transistors (Bias Resistor Built-in Transistors) llOutline Parameter Value SMT3 V -50V CC I -100mA C(MAX.) R 47k 1 R 10k SOT-346(SC-59) 2 llFeatures llInner 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 NPN Type: DTC144VKA 6) Lead Free/RoHS Compliant. llApplication Switching circuit, Inverter circuit, Interface circuit, Driver circuit llPackaging specifications Basic Package Taping Reel size Tape width Part No. Package ordering Marking size code (mm) (mm) unit.(pcs) DTA144VKA SMT3 2928 T146 180 8 3000 E56 www.rohm.com 1/5 20121023 - Rev.001 2012 ROHM Co., Ltd.
