DTA144W series PNP -100mA -50V Digital Transistors (Bias Resistor Built-in Transistors) Datasheet llOutline Parameter Value EMT3 UMT3 V -50V CC I -100mA C(MAX.) R 47k 1 DTA144WE DTA144WUA R SOT-416(SC-75A) SOT-323(SC-70) 22k 2 SMT3 llFeatures 1) Built-In Biasing Resistors 2) Built-in bias resistors enable the configuration of DTA144WKA an inverter circuit without connecting external SOT-346(SC-59) input resistors (see inner circuit) . 3) The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing llInner circuit 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 Types: DTC144W series 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) DTA144WE EMT3 1616 TL 180 8 3000 76 DTA144WUA UMT3 2021 T106 180 8 3000 76 DTA144WKA SMT3 2928 T146 180 8 3000 76 www.rohm.com 1/7 20121023 - Rev.001 2012 ROHM Co., Ltd.
