DTA124XM3T5G

Overview

The DTA124XM3T5G is a single PNP digital transistor (BRT) manufactured by onsemi, housed in an SOT-723 surface-mount package. It integrates internal biasing resistors to simplify circuit design and reduce component count. 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 base resistor value of 22 kOhms with a resistance ratio of 0.047. DC current gain (hFE) ranges from 80 to 130. Power dissipation is rated at 260 mW, and the unit operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates PNP bipolar junction transistor with built-in biasing network for simplified switching applications
• Utilizes compact SOT-723 three-terminal surface-mount packaging for space-constrained designs
• Provides high current handling capability up to 100 mA with robust thermal performance

Applications

• General-purpose switching circuits requiring pre-biased PNP configuration
• Interface drivers for logic-to-power level translation
• Load switching applications in consumer electronics and industrial control systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and material declarations directly with onsemi or authorized distributors prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements for SMD components.

Selection Notes

Select this component when a single PNP BRT with 50 V rating and 100 mA current capacity is required. The integrated 22 kOhm base resistor simplifies drive circuitry compared to discrete resistor-transistor combinations. Verify that the SOT-723 footprint matches the PCB layout constraints and that the thermal dissipation characteristics meet the application's power budget under worst-case operating conditions.

Part Context

This part belongs to the DTA124XM3 series of digital transistors from onsemi. It is designed as a replacement for discrete resistor-transistor networks, offering reduced board space and improved consistency in switching performance. The M3 suffix typically indicates lead-free and halogen-free construction compliant with environmental standards.

Replacement Considerations

Direct substitutes may include other PNP BRTs with similar VCEO and Ic ratings in compatible packages such as SOT-723 or SC-74. Verify pinout compatibility and resistor values before substitution. Cross-reference with onsemi's official cross-reference tools for validated alternatives.
