Overview
The DTC043TMT2L is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring an integrated base resistor (R1) to simplify biasing circuits. It operates with a collector-emitter voltage (VCEO) of 50 V and supports a continuous collector current (IC) of 100 mA. The device has a maximum power dissipation (Pd) of 150 mW and a transition frequency (fT) of 250 MHz. The DC current gain (hFE) ranges from 100 to 600 at IC = 5 mA and VCE = 10 V. It is housed in the SOT-723 (VMT3) surface-mount package, measuring 1.2 mm x 1.2 mm with a thickness of 0.55 mm.
Feature Summary
- Integrates a built-in base resistor to reduce component count and board space.
- Provides high current gain for efficient switching applications.
- Compact SOT-723 package suitable for dense surface-mount designs.
Applications
- General-purpose digital switching circuits
- Interface driver stages
- Logic level translation buffers
Procurement Notes
Verify the specific suffix TMT2L against the official ROHM datasheet to confirm the SOT-723 package and tape-and-reel quantity. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the part number with authorized distributors to avoid counterfeit components, as standard digital transistors are widely replicated.
Selection Notes
Select this component when a compact NPN switch with fixed base biasing is required. The 50 V rating and 100 mA current capacity suit low-power logic interfaces. Compare the 100-600 hFE range against load requirements. Verify that the SOT-723 footprint matches the PCB layout constraints compared to larger packages like SOT-23 or SOT-89.
Part Context
This part belongs to ROHM's DTC043 series of resistor-equipped bipolar transistors. The series offers various configurations including single-resistor (R1 only) and dual-resistor (R1/R2) options. The DTC043TMT2L specifically denotes the NPN variant with a single base resistor in the small SOT-723 package, designed for cost-sensitive and space-constrained consumer electronics.
Replacement Considerations
Compatible substitutes include DTC043TEBTL (SOT-416FL) and DTC043ZEBTL (SOT-416). Note that these alternatives use different footprints and require PCB redesign. For direct pin-compatible replacements in SOT-723, verify equivalent electrical parameters such as VCEO, IC, and R1 value with other manufacturers' offerings.
