Overview
The DTC114TMT2L is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of 50V and a continuous collector current of 100mA. The device incorporates a 10kΩ input resistor (R1) and a 47kΩ emitter-base resistor (R2), providing a typical DC current gain (hFE) of 68 at 5mA and 5V. Packaged in the compact VMT3 (SOT-723) surface-mount format measuring 1.2x1.2mm, it supports a maximum power dissipation of 150mW and functions reliably within a temperature range of -55°C to +150°C.
Feature Summary
- Integrated biasing resistors eliminate the need for external components, enabling straightforward inverter circuit configuration.
- Compact SOT-723 package facilitates high-density PCB layouts and automated surface-mount assembly.
- High breakdown voltage and current ratings support robust switching applications in low-power environments.
Applications
- General-purpose signal inversion and logic level shifting
- Driver circuits for small-signal loads and LEDs
- Switching elements in portable battery-powered devices
Procurement Notes
Verify the specific suffix MT2L against official ROHM documentation to confirm the VMT3 package and tape-and-reel quantity. Ensure compliance with RoHS directives and check for automotive qualification restrictions if applicable to the target system environment.
Selection Notes
Select this component when space constraints require a small footprint like SOT-723 alongside standard 10kΩ/47kΩ bias ratios. Compare hFE variations and saturation voltages against alternative packages such as SOT-23 or SOT-323 to ensure thermal and electrical performance meets the specific application requirements.
Part Context
This part belongs to the ROHM DTx series of digital transistors, which integrate pre-bias resistors directly onto the silicon die. The DTC114TMT2L specifically denotes the NPN polarity variant with defined resistance values, packaged in the VMT3 form factor for modern surface-mount manufacturing processes.
Replacement Considerations
Cross-reference with other ROHM parts sharing the same R1/R2 ratio and SOT-723 package, such as the DTC114YM or DTC114YCA variants, ensuring identical pinout and electrical characteristics before substitution.
