DTC044EMT2L

Overview

The DTC044EMT2L is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes a typical input resistor (R1) of 47 kOhms and an emitter-base resistor (R2) of 47 kOhms, maintaining a 1:1 resistance ratio. Packaged in the SOT-723 (VMT3) surface-mount format, it supports a maximum power dissipation of 150 mW and functions up to a transition frequency of 250 MHz. The component is rated for operation at temperatures up to +150°C.

Feature Summary

• Integrated pre-biasing resistors eliminate the need for external components, enabling straightforward inverter circuit configuration.
• Compact SOT-723 surface-mount package facilitates high-density PCB layouts.
• High-speed switching capability supported by a 250 MHz transition frequency.

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' against official ROHM documentation to confirm the tape-and-reel packaging quantity and marking details. Ensure compatibility with standard SOT-723 footprints during procurement planning. Cross-reference datasheet revisions to confirm RoHS compliance status and lead times directly from the manufacturer.

Selection Notes

Select this component when an NPN digital transistor with 47kΩ/47kΩ internal resistors is required in a compact SOT-723 package. Compare against the DTC044EEBTL if a smaller SC-89 footprint is needed, or consider complementary PNP types like the DTA044 series for push-pull configurations. Verify that the 50V rating meets the application's voltage requirements.

Part Context

This part belongs to the DTC044E series of digital transistors from ROHM Semiconductor. The series provides standardized NPN solutions with integrated biasing networks. The DTC044EMT2L variant specifically utilizes the VMT3 (SOT-723) package code, distinguishing it from other series members that may use different form factors such as SOT-23 or SC-89.

Replacement Considerations

Publicly confirmed substitutes include the DTC044EEBTL, which shares identical electrical characteristics but utilizes the SOT-416FL (SC-89) package. Designers must verify pinout compatibility and thermal performance differences when substituting between these package types.
