leshan radio company, ltd. p5?1/1 ? features 1)built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors. 2) the bias resistors consist of thinfilm resistors with complete isolation to allow positive biasing of the input,and parasitic effects are almost completely eliminated. 3) only the on/off conditions need to be set for operation, making device design easy. 4) higher mounting densities can be achieved. ? circuit schematic DTA115EKA absolute maximum ratings(t a =25 c) parameter symbol limits unit supply voltage v cc ?50 v input voltage v in ?40~+10 v output current i o ?20 ma i c(max.) ?100 dta115ee p d 150 mw power dissipation dta1 15eua/DTA115EKA 200 dta115esa 300 junction temperature t j 150 c storage temperature t stg ?55~+150 c elecrical characteristics(t a =25c) parameter symbol min. typ. max. unit conditions input voltage v i(off) ? ? ?0.5 v v cc = ?5v, i o =?100 a v i(on) ?3 ? ? v o = ? 0.3v, i o =?1ma output voltage v o(on) ? ?0.1 ?0.3 v i o / i i =?5ma/?0.25ma input current i i ? ? ?0.15 ma v i = ?5v output current i o(off) ? ? ?0.5 av cc = ?50v, v i = 0 v dc current gain g i 82 ? ? ? v o = ? 5v, i o =? 5ma input resistance r 1 70 100 130 k ? ? resistance ratio r 2 / r 1 0.8 1 1.2 ? ? transition frequency f t ? 250 ? mhz v ce =10v,i e =? 5 ma, f =100mhz* *transition frequency of the device digital transistors (built-in resistors) out gnd(+) out r1 r2 gnd(+) in in eiaj: sc? 59
