npn silicon surface mount transistor 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 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-23 package which is designed for low power surface mount applications. ? simplifies circuit design ? reduces board space and component count ? the sot-23 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. ? available in 8 mm embossed tape and reel. use the device number to order the 7 inch/3000 unit reel. replace ?t1? with ?t3? in the device number to order the13 inch/10,000 unit reel. 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 total power dissipation @ t a = 25 c (note 1.) derate above 25 c p d * 246 1.5 mw c/w device marking and resistor values device marking r1(k) r2(k) lmun2211lt1g a8a 10 10 lmun2212lt1g a8b 22 22 lmun2213lt1g a8c 47 47 lmun2214lt1g a8d 10 47 lmun2215lt1g a8e 10 lmun2216lt1g a8f 4.7 lmun2230lt1g a8g 1.0 1.0 lmun2231lt1g a8h 2.2 2.2 a8j 4.7 4.7 lmun2233lt1g a8k 4.7 47 lmun2234lt1g a8l 22 47 lmun2235lt1g a8m 2.2 47 lmun2236lt1g a8n 100 lmun2237lt1g a8p 47 1. device mounted on a fr-4 glass epoxy printed circuit board using the minimum recommended footprint. lmun2232lt1g leshan radio company, ltd. device package shipping lmun2211lt1g sot23 3000/tape&reel 10000/tape&reel lmun2211lt3g sot23 we declare that the material of product compliance with rohs requirements. lmun2240lt1g a8t 47 lmun2241lt1g a8u 100 lmun2238lt1g a8r 2.2 22 100 rev.a 1/7 1 3 2 lmun2211lt1g series s-lmun2211lt1g series ordering information s- prefix for automotive and other applications requiring unique site and control change requirements; aec-q101 qualified and ppap capable. ?
