DTA144E 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
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 :DTC144E series
6) Complex transistors :EMB2 /UMB5N /IMB2A
l
Inner circuit
/EMA2 /UMA2N /FMA2A （PNP type）
7) Lead Free/RoHS Compliant.
