DTA114TM3T5G

Overview

The DTA114TM3T5G is a single PNP digital transistor manufactured by onsemi, housed in an SOT-723 surface-mount package. It integrates a built-in base resistor with a typical value of 10 kOhms to simplify circuit design. The device supports a maximum continuous collector current of 100 mA and withstands a collector-emitter voltage (VCEO) of up to 50 V. Key electrical characteristics include a minimum DC current gain (hFE) ranging from 160 to 350 and a maximum power dissipation of 260 mW. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates a single NPN or PNP transistor with a pre-biased internal resistor to reduce component count and board space.
• Designed for high-speed switching applications with low saturation voltage and fast turn-on/turn-off times.
• Utilizes a compact SOT-723 three-pin surface-mount package suitable for dense PCB layouts.

Applications

• General-purpose switching in consumer electronics and industrial control systems.
• Driver circuits for relays, solenoids, and small motors.
• Logic level translation and buffer stages in microcontroller interfaces.

Procurement Notes

Verify the specific suffix 'T5G' to confirm the tape-and-reel packaging format and lead-free compliance status. Confirm RoHS directive adherence through official manufacturer documentation or certified distributor declarations. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is required. Cross-reference the manufacturer part number against the latest datasheet revision to validate any potential pinout or electrical specification updates.

Selection Notes

Select this component when a compact PNP switching solution with integrated biasing is required. Compare the 10 kOhm internal resistance against application drive requirements to ensure adequate base current. Evaluate the 50 V collector-emitter rating against peak circuit voltages to prevent breakdown. Consider the SOT-723 thermal performance and power dissipation limits under continuous load conditions.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from onsemi. It serves as a direct replacement for older discrete resistor-transistor combinations, offering improved consistency and reduced assembly time. The TM3 suffix typically denotes specific automotive or high-reliability qualification standards depending on the manufacturer's current nomenclature guidelines.

Replacement Considerations

Direct substitutes include the DTC114TM3T5G (NPN counterpart) for complementary designs. Other compatible PNP digital transistors with similar 10 kOhm base resistors and SOT-723 packages should be verified for matching hFE ranges and VCEO ratings before substitution.
