DTC144TT1G

Overview

The DTC144TT1G is an NPN silicon Bias Resistor Transistor (BRT) designed to replace a single transistor and its external resistor bias network. It integrates a monolithic bias network consisting of a series base resistor (R1) and a base-emitter resistor (R2). The device features a collector-emitter voltage (VCEO) of 50 Vdc, a continuous collector current (IC) of 100 mAdc, and an input resistance R1 of 47 kΩ with an open R2 configuration. Housed in the SC-59 surface mount package, it simplifies circuit design while reducing board space and component count.

Feature Summary

• Integrates a single NPN transistor with a monolithic bias network comprising a series base resistor and a base-emitter resistor to eliminate individual components.

Applications

• Level shifting between logic circuits and 12 or 24 Volt loads
• Open collector inverter configurations for signal inversion
• Unregulated current source applications

Procurement Notes

Verify the specific ordering suffix 'T' against the manufacturer's official documentation to confirm shipping format details. Confirm that the requested part number matches the preferred device designation listed in the datasheet to ensure availability and correct packaging specifications.

Selection Notes

Select this component when a compact solution is required to replace discrete transistors and bias resistors. Ensure the 50 V collector-emitter voltage rating and 100 mA current capacity meet the circuit requirements. Verify that the SC-59 package dimensions align with the available PCB footprint constraints.
