LESHAN RADIO COMPANY, LTD. Digital transistors (built-in resistors) * Features 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 thinfilm 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 device design easy. * Structure PNP digital transistor (Built-in resistors type) *Equivalent circuit R1 IN DTA124EKA DTA124ECA OUT R2 GND(+) IN OUT GND(+) 2.9 + 0.2 1.9+ 0.2 + 0.2 0.1 1.1 - 0.95+0.95 0.8 + 0.1 (2) + 0.2 - 0.1 1.3 2.8+ 0.2 1.6 0.45 + 0.1 0 ~ 0.1 0 ~ 0.1 (3) 0.4 0.15 + 0.1 - 0.05 0.3 ~ 0.6 (3) + 0.1 - 0.06 (1) GND (2) IN (3) OUT + 0.2 - 0.1 (2) (1) + 0.2 - 0.1 (1) 0.95 0.95+ 0.95 2.4+ 0.2 2.9 + 0.2 1.9+ 0.2 0.2Min 0.4 (1) GND (2) IN (3) OUT + 0.1 0.06 0.15 - + 0.1 - 0.05 All terminals have same dimensions All terminals have same dimensions DTA124EKA DTA124ECA EIAJ: SC-- 59 * EIAJ: SOT-- 23 Absolute maximum ratings(Ta=25 C) limits Parameter symbol (DTA124EKA DTA124ECA ) Supply voltage Input voltage V cc V IN IO -50 -40~+10 -30 -100 200 150 -55~+150 Output current Power dissipation Junction temperature Storage temperature I C(Max.)
