DTD123EK Datasheet 500mA/50V Digital transistor (with built-in resistors) llOutline Parameter Value SMT3 V 50V CC I 500mA C(MAX.) R 2.2k 1 SOT-346 R 2.2k SC-59 2 llFeatures llInner circuit 1)Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors.(see equivalent circuit) 2)The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of almost completely eliminating parasitic effects. 3)Only the on/off conditions need to be set for operation, making the device desigh easy. llApplication INVERTER, INTERFACE, DRIVER llPackaging specifications Basic Package Taping Reel size Tape width Part No. Package ordering Marking size code (mm) (mm) unit.(pcs) DTD123EK SMT3 2928 T146 180 8 3000 F22 www.rohm.com 1/5 20150730 - Rev.001 2015 ROHM Co., Ltd.
