Overview
The DTC144TM3T5G is a single NPN digital transistor from onsemi, housed in an SOT-723 surface-mount package. It integrates a built-in bias resistor network with a typical input resistance of 47 kOhms and a resistor ratio of 1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 260 mW, with a minimum DC current gain (hfe) ranging from 80 to 140. It operates within a temperature range of -55°C to +150°C and meets AEC-Q101 automotive qualification standards.
Feature Summary
- Integrates a single NPN transistor with a built-in bias resistor network for simplified circuit design.
- Features a compact SOT-723 three-terminal surface-mount package for space-constrained applications.
- Qualified for automotive electronics under the AEC-Q101 standard.
Applications
- General-purpose switching circuits
- Logic level translation interfaces
- Driver circuits for small-signal loads
Procurement Notes
Verify the specific ordering suffix TM3T5G against the manufacturer's official datasheet to confirm pinout configuration and internal resistor values. Ensure the component meets RoHS compliance requirements for the target assembly process. Confirm that the SOT-723 package dimensions align with the PCB footprint specifications before finalizing procurement orders.
Selection Notes
Select this component when a single NPN switch with integrated base biasing is required. The 47 kOhm input resistance suits direct interfacing with standard logic outputs. Verify that the 50 V voltage rating and 100 mA current capacity exceed the maximum load requirements of the application circuit.
Part Context
This part belongs to the DTC144EM3 series of biased resistor transistors manufactured by onsemi. It shares the same functional architecture as other members of the family but utilizes the TM3 variant designation within the SOT-723 package format. The product line focuses on providing integrated solutions to reduce external component count in digital switching applications.
Replacement Considerations
The DTC144EM3T5G is a documented alternative within the same series offering identical electrical characteristics and pinout compatibility. Verify that any substitute maintains the AEC-Q101 qualification if automotive reliability is required.
