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 DTA143EKA DTA143ECA 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 0.95+0.95 + 0.2 0.1 1.1 - 0.8 + 0.1 (2) 1.6 + 0.2 - 0.1 (1) 0 ~ 0.1 2.8+ 0.2 PNP digital transistor (with built-in resistors) •Equivalent circuit (3) OUT 0.4 R2 GND(+) IN 0.15 + 0.1 - 0.05 + 0.1 - 0.06 All terminals have same dimensions OUT (1) GND (2) IN (3) OUT 0.3 ~ 0.6 IN R1 DTA143EKA EIAJ: SC— 59 GND(+) 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 0.4 0.15 + 0.1 - 0.05 + 0.1 - 0.06 All terminals have same dimensions (1) GND (2) IN (3) OUT DTA143ECA EIAJ: SOT— 23 • Absolute maximum ratings(Ta=25 °C) Parameter symbol limits unit Supply voltage Input voltage V cc V IN IO –50 –30~+10 –100 –100 200 150 –55~+150 V V Output current Power dissipation Junction temperature Storage temperature I C(Max.)
