LESHAN RADIO COMPANY, LTD. Digital transistors (built-in resistors) * Features DTC143EKA 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 2.9 + 0.2 1.9+ 0.2 PNP digital transistor ( built-in resistors) * Equivalent circuit 1.1 0.95+0.95 0.8 + 0.1 (2) OUT 0 ~ 0.1 2.8+ 0.2 (3) R2 GND IN 0.4 OUT 0.15 + 0.1 - 0.05 + 0.1 - 0.06 0.3 ~ 0.6 IN 1.6 + 0.2 - 0.1 (1) R1 + 0.2 - 0.1 (1) GND (2) IN (3) OUT All terminals have same dimensions GND EIAJ: SC-- 59 * Absolute maximum ratings(Ta=25 C) Parameter symbol Supply voltage V Input voltage V IN IO Output current Power dissipation Junction temperature Storage temperature cc I C(Max.)
