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). DTC114EKA DTC114ECA 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 2.9 + 0.2 1.9+ 0.2 PNP digital transistor (with built-in resistors) •Equivalent circuit 1.1 0.95+0.95 0.8 + 0.1 (2) + 0.2 - 0.1 1.6 OUT (3) R2 0.4 0.15 + 0.1 - 0.05 (1) GND (2) IN (3) OUT 0.3 ~ 0.6 R1 0 ~ 0.1 2.8+ 0.2 (1) IN + 0.2 - 0.1 + 0.1 - 0.06 GND(+) All terminals have same dimensions IN DTA114EKA OUT GND(+) EIAJ: SC— 59 2.9 + 0.2 1.9+ 0.2 0.95+ 0.95 0.95 + 0.2 - 0.1 0.45 + 0.1 (2) 0 ~ 0.1 2.4+ 0.2 1.3 + 0.2 - 0.1 (1) (3) 0.2Min 0.15 0.4 + 0.1 - 0.05 + 0.1 - 0.06 All terminals have same dimensions (1) GND (2) IN (3) OUT DTA114ECA EIAJ: SOT—23 • Absolute maximum ratings(Ta=25 °C) Parameter symbol limits unit Supply voltage Input voltage V cc V IN IO –50 –10~+40 50 100 200 150 –55~+150 V V Output current Power dissipation Junction temperature Storage temperature I C(Max.)
