DTC124EM3T5G

Overview

The DTC124EM3T5G is a single NPN digital transistor manufactured by onsemi, housed in an SOT-723 surface-mount package. It integrates internal biasing resistors to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical base resistor (R1) of 1 kOhm and an emitter-base resistor (R2) of 4.7 kOhms, with a resistance ratio of 1. Minimum DC current gain (hFE) ranges from 80 to 140. Power dissipation is rated at 260 mW, with an operating temperature range spanning from -55°C to +150°C.

Feature Summary

• Integrates built-in bias resistors to eliminate the need for external input components in inverter circuits.
• Provides simplified switching functionality where only on/off conditions require setting for operation.
• Designed for surface-mount technology applications requiring compact footprint solutions.

Applications

• Inverter circuits
• Interface driving applications

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and check for any product change notifications regarding manufacturing site or material composition updates before integration into final designs.

Selection Notes

Select this component when a single NPN switch with integrated biasing is required. Ensure the 50V voltage rating and 100mA current capacity meet system demands. Consider the SOT-723 package constraints for thermal management and PCB layout space availability.

Part Context

This part belongs to the DTC124EM3 series of pre-biased transistors. It serves as a complementary counterpart to PNP types like the DTA124 series. The 'M3' suffix typically indicates lead-free packaging compliant with environmental directives.

Replacement Considerations

Direct substitutes within the same family include DTC124XEB. Verify pinout compatibility and electrical parameter equivalence before substitution.
