DTA043TMT2L

Overview

The DTA043TMT2L is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device incorporates an internal base resistor (R1) of 4.7 kOhms and an emitter-base resistor (R2) of 4.7 kOhms. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at specified test conditions and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW, and the component is housed in a compact VMT3 (SOT-723) surface-mount package.

Feature Summary

• Integrates dual bias resistors to reduce external component count and PCB space
• Optimized for high-speed switching applications with a 250 MHz transition frequency
• Provides consistent hFE performance across operating temperatures

Applications

• General-purpose logic level shifting and interface circuits
• Driver stages for relays, solenoids, and small motors
• Switching elements in portable battery-powered devices

Procurement Notes

Verify the specific suffix TMT2L against the manufacturer's latest datasheet to confirm packaging details and tape-and-reel specifications. Ensure compatibility with RoHS3 directives if required by the target market regulations. Cross-reference the ordering code with authorized distributors to confirm current production status and availability constraints.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for space-constrained designs. Compare the 4.7 kOhm resistor values against alternative models like DTA043XMT2L if different bias ratios are needed. Verify that the 150 mW power dissipation rating meets the thermal requirements of the intended application environment.

Part Context

This part belongs to Rohm's standard DTA043 series of digital transistors. It shares the same electrical profile as other variants in the family but utilizes the VMT3 package. The series is designed for general-purpose switching, distinct from automotive-grade AEC-Q101 qualified parts within the broader product line.

Replacement Considerations

Direct pin-compatible substitutes include DTA043TM and DTC043TM (NPN version). For identical PNP characteristics in the same package, verify DTA043XMT2L or DTA043ZMT2L, noting potential differences in internal resistor ratios.
