DTA144EET1

Overview

The DTA144EET1 is a PNP silicon surface mount Bias Resistor Transistor (BRT) from onsemi, housed in the SC-75/SOT-416 package. It integrates a single transistor with a monolithic bias network consisting of two resistors: R1 and R2. The device features a collector-emitter voltage rating of 50 Vdc and a maximum collector current of 100 mAdc. Electrical characteristics include a DC current gain (hFE) minimum of 80 at IC = 5.0 mA and VCE = 10 V. The integrated resistors are specified as R1 = 47 kOhms and R2 = 47 kOhms. Thermal dissipation is rated at 200 mW on an FR-4 board with minimum pads.

Feature Summary

Integrates a PNP transistor with a monolithic bias resistor network to replace discrete components
Designed for low power surface mount applications using the SC-75/SOT-416 package
AEC-Q101 qualified and PPAP capable for automotive and high-reliability requirements

Applications

Inverter circuits
Interface logic drivers
General-purpose switching applications requiring simplified bias networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and lead-free status. Confirm that the component meets AEC-Q101 qualification requirements if intended for automotive use. Ensure the selected variant matches the required resistor values and thermal performance specifications for the target application environment.

Selection Notes

Select this component when a PNP digital transistor with equal base and emitter-base resistors of 47 kOhms is required. The SC-75 package is suitable for wave or reflow soldering processes. Consider the thermal resistance and power dissipation limits relative to the ambient temperature and PCB pad size to ensure reliable operation within the specified junction temperature range.

Part Context

This part belongs to the DTA114EET1 Series, which includes various PNP BRT configurations with different resistor ratios. The series is designed to reduce board space and component count by integrating the bias network directly into the transistor package. The DTA144EET1 specifically utilizes the 47k/47k resistor configuration within this family.
