DTC144EET1

Overview

The DTC144EET1 is an NPN silicon Bias Resistor Transistor (BRT) from the DTC114EET1 series, manufactured by onsemi. It integrates a single transistor with a monolithic bias network consisting of two resistors: a series base resistor (R1) and a base-emitter resistor (R2). The device features maximum ratings of 50 Vdc for both collector-base (VCBO) and collector-emitter (VCEO) voltages, with a continuous collector current (IC) of 100 mAdc. The integrated resistors are specified at 47 kΩ each. It operates within a junction temperature range of -55 to +150 °C and utilizes the SC-75/SOT-416 surface mount package.

Feature Summary

Integrates a single NPN transistor with a monolithic bias resistor network to replace discrete components
Reduces board space and component count in circuit designs
SC-75/SOT-416 package designed for low power surface mount applications
Modified gull-winged leads absorb thermal stress during wave or reflow soldering

Applications

Level shifting between 12/24 Volt circuits and logic levels
Open collector inverter configurations
Unregulated current source implementations

Procurement Notes

Verify the specific ordering suffix to confirm lead-free status and packaging format. Confirm that the device code matches the required resistor values. Ensure the tape and reel specifications align with automated assembly requirements. Check the manufacturer's latest documentation for any updates to the marking diagram or shipping information before finalizing orders.

Selection Notes

Select this component when a fixed 47 kΩ base-to-collector and base-to-emitter resistance configuration is required. Verify that the 100 mA collector current rating meets the load requirements. Ensure the operating voltage does not exceed the 50 Vdc breakdown limits. Consider the thermal resistance characteristics if high ambient temperatures are expected in the application environment.

Part Context

This part belongs to the DTC114EET1 series of NPN Bias Resistor Transistors. The series includes various combinations of internal resistors to suit different biasing needs. The DTC144EET1 specifically provides symmetric 47 kΩ resistors. Other variants in the series offer different resistance ratios or values, such as the DTC114EET1 with 10 kΩ resistors.

Replacement Considerations

Direct substitutes include other DTC114EET1 series parts with identical pinouts and electrical characteristics but different resistor values if the circuit allows. Verify compatibility with the SC-75/SOT-416 package dimensions. Ensure any replacement maintains the same NPN polarity and voltage/current ratings.
