DTA144TM3T5G

Overview

The DTA144TM3T5G is a PNP Bias Resistor Transistor (BRT) from onsemi, housed in an SOT-723 package. It integrates a single transistor with a monolithic bias network consisting of a series base resistor (R1 = 47 kOhms) and a base-emitter resistor (R2). Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 Vdc, continuous collector current (IC) of 100 mAdc, and DC current gain (hFE) ranging from 120 to 250 at IC = 5.0 mA and VCE = 10 V. The device operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Integrates a single PNP transistor with a monolithic bias network containing two resistors to replace discrete components.
• Simplifies circuit design by reducing board space and component count.
• Qualified for automotive applications under AEC-Q101 standards and capable of PPAP.

Applications

• Automotive systems requiring unique site and control change requirements.
• General-purpose digital switching circuits.
• Logic level translation interfaces.

Procurement Notes

Verify the specific ordering suffix 'T5G' corresponds to the SOT-723 package and tape & reel shipping configuration. Confirm that the part marking '6T' matches the required identification for assembly traceability. Ensure compliance with RoHS and Pb-Free specifications if environmental regulations apply to the final product.

Selection Notes

Select this component when a PNP digital transistor with a 47 kOhm base resistor is required. Verify that the 50 V collector-emitter voltage rating meets the circuit's maximum operating voltage. Consider the SOT-723 package dimensions for PCB layout constraints and ensure the thermal dissipation characteristics are sufficient for the application's power requirements.

Part Context

This device belongs to the DTA144TM3 series of PNP digital transistors. It shares functional similarities with other BRTs like the DTA144TE but differs in packaging. The TM3 designation indicates the SOT-723 form factor, which offers a smaller footprint compared to standard SOT-23 packages while maintaining similar electrical performance characteristics.

Replacement Considerations

Direct substitutes include DTA144TE (SC-75 package) and MUN2140 (SC-59 package), provided pinout compatibility and package dimensions are verified. Cross-reference electrical parameters such as hFE and VCEO to ensure equivalent performance in the target circuit.
