bias resistor transistors pnp 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 sc-89 package which is designed for low power surface mount applications. ldta114eet1g series ? simplifies circuit design reduces board space reduces component count the sc-89 package can be soldered using wave or reflow. the modified gull-winged leads absorb thermal stress during soldering eliminating the possibility of damage to the die. sc-89 pin 3 collector (output) pin 2 emitter (ground) pin 1 base (input) r 1 r 2 leshan radio company, ltd. we declare that the material of product compliance with rohs requirements. 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 rating symbol value unit total device dissipation, fr?4 board (note 1) @ t a = 25 c derate above 25 c p d 200 1.6 mw mw/ c thermal resistance, junction?to?ambient (note 1) r ja 600 c/w total device dissipation, fr?4 board (note 2) @ t a = 25 c derate above 25 c p d 300 2.4 mw mw/ c thermal resistance, junction?to?ambient (note 2) r ja 400 c/w junction and storage temperature range t j , t stg ?55 to +150 c stresses exceeding maximum ratings may damage the device. maximum ratings are stress ratings only. functional operation above the recommended operating conditions is not implied. extended exposure to stresses above the recommended operating conditions may affect device reliability. 1. fr?4 @ minimum pad. 2. fr?4 @ 1.0 1.0 inch pad. rev.o 1/12
