DDC144TU

DUAL NPN TRANSISTORS WITH 47K OHM BASE RESISTOR

General Description

• DDC144TU is best suited for logic switching applications

using control circuits like micro-controllers, comparators,

etc. It features two discrete NPN transistors which can

support maximum continuous current of 100 mA. NPN

transistors can be used as a control and also these can

be biased using higher supply voltages due to the built in

current limiting base resistor of 47 K Ohm. The

component devices can be used as a part of a circuit or

as a stand alone discrete device.

Features

• Built in Base Resistors

• Epitaxial Planar Die Construction

• Lead Free By Design/RoHS Compliant (Note 1)

• "Green" Device (Note 2)
