DTD523YMT2L

Overview

The DTD523YMT2L is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It is housed in a compact SOT-723 (VMT3) surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device incorporates a typical input resistance of 2.2 kΩ and an emitter-base resistance of 10 kΩ. It offers a minimum DC current gain of 33 at 100 mA with a 2 V supply. The component supports a power dissipation of 150 mW and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrated biasing resistors eliminate the need for external input components, enabling straightforward inverter circuit configuration.
• Compact SOT-723 surface-mount packaging facilitates high-density board layouts.
• High current handling capability of 100 mA suitable for general switching applications.

Applications

• General-purpose logic level shifting and signal inversion
• Driver circuits for small-signal loads
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix 'T2L' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering quantity aligns with standard reel sizes to avoid partial reel handling issues during production.

Selection Notes

Select this component when a single NPN digital transistor with 50 V rating and 100 mA output is required. The 2.2 kΩ input resistor value is appropriate for direct interfacing with standard logic outputs. Consider complementary PNP types from the DTA123E series if push-pull configurations are necessary for the application.

Part Context

This part belongs to the ROHM Digital Transistor family, which integrates transistors and bias resistors into a single package. The DTC123YM series serves as the base model identifier, while the T2L suffix denotes the specific SOT-723 package and taping configuration used for surface-mount technology assembly lines.

Replacement Considerations

The DTC123YM is listed as a recommended product within the same family. Verify pinout compatibility and electrical parameter equivalence before substitution. Other variants in the DTC123 series may offer different resistor ratios or package options.
