| 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 isola tion 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 PNP digital transistor (with built-in resistors) 1.9+ 0.2 *Equivalent circuit 0.95+ 0.95 (1) (2) 2.8+ 0.2 + 0.2 - 0.1 DTD143EK DTD143ES 0.8 + 0.1 0 ~ 0.1 (3) 1.6 IN R1 R2 OUT 0.4 + 0.1 - 0.05 0.15 - + 0.1 0.06 All terminals have same dimensions GND IN GND 2.9 + 0.2 1.9+ 0.2 0.95+0.95 (1) (2) 2.4+ 0.2 + 0.2 - 0.1 OUT EIAJ: SC-- 59 0.95 + 0.2 - 0.1 0.45 + 0.1 (3) 0.15 + 0.1 - 0.06 1.3 0.3 ~ 0.6 (1) GND (2) IN (3) OUT DTD143EK 0 ~ 0.1 0.2Min + 0.1 - 0.05 0.4 (1) GND (2) IN (3) OUT All terminals have same dimensions DTD143ES EIAJ: SOT-- 23 * Absolute maximum ratings(Ta=25 C) limits( DTC143E ) Parameter symbol K S V V mA mW C C V cc V IN IC Pd Tj T stg 50 -10~+30 500 200 150 -55~+150 300 unit Supply voltage Input voltage Output current Power dissipation Junction temperature Storage temperature P18-1/2 LESHAN RADIO COMPANY, LTD.
