DTA044E series

PNP -100mA -50V Digital Transistors (Bias Resistor Built-in Transistors)

Outline

Features

1) Built-In Biasing Resistors, R1 = R2 = 47kW.

2) Built-in bias resistors enable the configuration of
an inverter circuit without connecting external
input resistors (see inner circuit).

3) The bias resistors consist of thin-film resistors

with complete isolation to allow negative biasing

of the input. They also have the advantage of

l

Inner circuit

completely eliminating parasitic effects.

4) Only the on/off conditions need to be set for
operation, making the circuit design easy.

5) Complementary NPN Types :DTC044E series

6) Lead Free/RoHS Compliant.
