DTC124XM3T5G

Overview

The DTC124XM3T5G is an NPN Bipolar Resistor-Integrated Transistor (BRT) manufactured by onsemi. It integrates a single NPN transistor with two internal bias resistors in a compact surface-mount package. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 4.7 kOhms and a power dissipation rating of 260 mW. It operates within a temperature range from -55°C to +150°C and is housed in an SOT-723-3 package.

Feature Summary

• Integrates NPN transistor with dual bias resistors for simplified circuit design
• Provides high-density packaging suitable for space-constrained applications
• Offers robust thermal performance with extended operating temperature range

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Level shifting applications

Procurement Notes

Verify the specific suffix T5G against official onsemi documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status through the manufacturer's latest product compliance declarations. Ensure the ordering part number matches the exact electrical characteristics required for the target application design.

Selection Notes

Select this component when a single NPN BRT with approximately 4.7 kOhm base resistance is required. Compare the 50 V VCEO and 100 mA IC limits against circuit demands. Evaluate the SOT-723-3 footprint against available PCB real estate. Verify thermal requirements against the 260 mW dissipation rating under expected operating conditions.

Part Context

This part belongs to the DTC124X series of digital transistors. It shares the same internal resistor network topology as other variants in the family but differs in package or specific resistance values compared to siblings like the DTC123 series. It serves as a discrete solution replacing multiple external components in low-power switching roles.

Replacement Considerations

Direct substitutes may include other NPN BRTs with similar 50V/100mA ratings and comparable base resistance, such as parts from the DTC124 series family. Verify pinout compatibility and thermal characteristics before substitution.
