DTB114GK
PNP -500mA -50V Digital Transistors (Bias Resistor Built-in Transistors)
lOutline
lFeatures
lInner circuit
1) Built-In Biasing Resistors
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) Complementary NPN Types :DTD114GK
5) Lead Free/RoHS Compliant.
