leshan radio company, ltd. bias resistor transistors npn silicon surface mount transistors with monolithic bias resistor network this new series of digital transistors is designed to replace a single device and its external resistor bias network. the brt (bias resistor transistor) contains a single transistor with a monolithic bias network consisting of two resistors; a series base resistor and a base-emitter resistor. the brt eliminates these individual components by integrating them into a single device. the use of a brt can reduce both system cost and board space. the device is housed in the sot-723 package which is designed for low power surface mount applications. ldtc114em3t5g maximum ratings (t a = 25 c unless otherwise noted) rating symbol value unit collector-base voltage v cbo 50 vdc collector-emitter voltage v ceo 50 vdc collector current i c 100 madc thermal characteristics characteristic symbol max unit total device dissipation t a = 25 c derate above 25 c p d 260 (note 1) 600 (note 2) 2.0 (note 1) 4.8 (note 2) mw thermal resistance ? junction-to-ambient r ja 480 (note 1) 205 (note 2) c/w storage temperature range t stg ?55 to +150 c xx = specific device code m = date code marking diagram 3 2 1 xx m mw/ c ? simplifies circuit design ? reduces component count ? the sot-723 package can be soldered using wave or reflow. ? available in 4 mm, 8000 unit tape & reel ? these are pb-free devices. ? reduces board space series sot-723 1 2 3 pin 3 collector (output) pin 2 emitter (ground) pin 1 base (input) r1 r2 c t j 150 junction temperature 1. fr?4 @ minimum pad 2. fr?4 @ 1.0 x 1.0 inch pad rev.o 1/14 ldtc114em3t5g s-ldtc114em3t5g series ? and control change requirements; aec-q101 qualified and ppap capable. s- prefix for automotive and other applications requiring unique site
