DTB123EK -500mA/-50V Digital transistor (with built-in resistors) Datasheet llOutline Parameter Value SOT-346 V -50V CC SC-59 I -500mA C(MAX.) R 2.2k 1 R 2.2k (SMT3) 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 positive 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) SOT-346 DTB123EK 2928 T146 180 8 3000 F12 (SMT3) www.rohm.com 1/5 20150821 - Rev.002 2015 ROHM Co., Ltd.
