DTC024XMT2L

Overview

The DTC024XMT2L is a single NPN digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors within a VMT3 (SOT-723) surface-mount package. It operates with a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. The device includes an internal base resistor (R1) of 22kΩ and an emitter-base resistor (R2) of 22kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 56 at 5mA/10V, a saturation voltage of 300mV at 500µA/10mA, and a transition frequency of 250MHz. Power dissipation is rated at 150mW.

Feature Summary

• Integrates NPN bipolar junction transistor with dual thin-film bias resistors for simplified circuit design
• Provides complete isolation between bias resistors to allow negative input biasing without parasitic effects
• Utilizes compact VMT3 surface-mount packaging suitable for high-density board layouts

Applications

• Inverter circuits requiring direct logic interface
• Driver stages for low-power switching applications
• General-purpose digital signal buffering

Procurement Notes

Verify the specific suffix MT2L against the target Bill of Materials to ensure compatibility with the required VMT3 tape-and-reel packaging format. Confirm that the standard commercial grade meets the environmental operating temperature range requirements for the intended application, as automotive variants carry distinct suffixes.

Selection Notes

Select this component when a 50V NPN switch with matched 22kΩ biasing resistors is required. The 250MHz transition frequency supports moderate-speed digital switching. Ensure the 150mW power dissipation limit accommodates the thermal constraints of the VMT3 footprint in the final assembly design.

Part Context

This part belongs to the DTC024 series of Rohm's standard digital transistors. It serves as the NPN counterpart to PNP devices like the DTA024 series. The product line is designed to replace discrete resistor-transistor networks, reducing component count and assembly time in consumer electronics and industrial control systems.

Replacement Considerations

Cross-reference with DTC024EUBTL for SOT-323FL-3 packaging or DTC024EE3TL for SOT-416-3 packaging if pinout compatibility allows. Verify that alternative packages maintain the same 22kΩ/22kΩ resistor ratio and 50V rating.
