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 (with built-in resistors) •Equivalent circuit 2.9 + 0.2 DTB143EK DTB143EC + 0.2 0.1 1.9+ 0.2 0.95+0.95 1.1 - 0.8 + 0.1 (2) 0 ~ 0.1 2.8+ 0.2 1.6 + 0.2 - 0.1 (1) 0.4 IN R1 0.15 + 0.1 - 0.05 0.3 ~ 0.6 (3) + 0.1 - 0.06 OUT All terminals have same dimensions DTB143EK R2 GND(+) IN (1) GND (2) IN (3) OUT EIAJ: SC— 59 OUT 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 DTB143EC EIAJ: SOT— 23 • Absolute maximum ratings(Ta=25 °C) Parameter Supply voltage Input voltage Output current Power dissipation Junction temperature Storage temperature symbol limits unit V cc V IN IC Pd Tj T stg –50 –30~+10 –500 V V mA mW °C °C 200 300 150 –55~+150 P10–1/2 DTB143EK DTB143EC • Elecrical characteristics(T =25°C) a Parameter symbol Min.
