DTA143TM3T5G

Overview

The DTA143TM3T5G is a single PNP digital transistor manufactured by onsemi, housed in an SOT-723 surface-mount package. It features a built-in base resistor with a typical value of 4.7 kOhms and a resistance ratio of 1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 160 at 5 mA and 10 V, a maximum saturation voltage of 250 mV at 1 mA base and 10 mA collector currents, and a power dissipation rating of 260 mW. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates a pre-biased PNP transistor with a single internal base resistor for simplified circuit design.
• Provides high current gain and low saturation voltage for efficient switching performance.
• Utilizes a compact SOT-723 package suitable for space-constrained surface-mount applications.

Applications

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

Procurement Notes

Verify the specific ordering suffix T5G to confirm the reel packaging configuration and tape width. Ensure compliance with RoHS directives as indicated in official documentation. Confirm the manufacturer part number matches exactly to avoid confusion with similar series variants or alternative packaging options such as cut tape.

Selection Notes

Select this component when a single PNP digital transistor with a 4.7 kOhm base resistor is required. Consider the 50 V voltage rating and 100 mA current limit against load requirements. The SOT-723 footprint must be compatible with the PCB layout. Verify thermal management needs given the 260 mW power dissipation limit in the chosen application environment.

Part Context

This part belongs to the DTA143TM3 series of digital transistors from onsemi. It is designed as a replacement for discrete resistor-transistor networks, reducing component count and board space. The M3 suffix typically indicates lead-free and halogen-free compliance, aligning with modern environmental standards for semiconductor components.

Replacement Considerations

Check for direct pin-compatible alternatives within the same DTA143 family that may offer different resistor values or packaging options. Verify that any substitute maintains the same PNP polarity, voltage ratings, and thermal characteristics to ensure functional equivalence without redesigning the surrounding circuitry.
