Overview
The DTC043XMT2L is an NPN digital transistor from ROHM Semiconductor, featuring built-in bias 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 4.7 kOhms and an emitter-base resistor (R2) of 10 kOhms. Packaged in the compact VMT-3 (SOT-723) surface-mount format, it offers a power dissipation of 150 mW and a transition frequency of 250 MHz. The component is RoHS compliant and designed for general-purpose switching applications.
Feature Summary
- Integrated bias resistors eliminate the need for external components, enabling straightforward inverter circuit configuration.
- Thin-film resistors provide complete isolation, allowing negative input biasing while eliminating parasitic effects.
- Compact SMD package supports automated surface-mount assembly processes.
Applications
- General-purpose digital logic interface circuits
- Inverter configurations requiring minimal external components
- Driver circuits for low-power loads
Procurement Notes
Verify the specific suffix 'T2L' against the manufacturer's latest datasheet to confirm tape-and-reel specifications and packaging quantity. Confirm RoHS compliance status directly with the supplier documentation. Ensure the component source matches the authorized distributor list to avoid counterfeit parts. Check for any recent lifecycle changes or obsolescence notices prior to final procurement.
Selection Notes
Select this component when a single NPN digital transistor with a 4.7k/10k resistor ratio is required. Verify that the 100 mA collector current and 50 V breakdown voltage meet the load requirements. Consider the VMT-3 package dimensions for PCB layout constraints. Compare against complementary PNP types if both polarities are needed in the design.
Part Context
This part belongs to the DTC043XM series of standard digital transistors. It is categorized as a standard-grade product intended for general electronic equipment. The manufacturer explicitly states that this product is not recommended for use in automotive devices due to its standard reliability classification.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official cross-reference lists or contact the manufacturer for qualified alternatives.
