Overview
The DTC114TUBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a collector-emitter voltage (VCEO) of 50 V and supports a continuous collector current of 100 mA. The device incorporates a 10 kOhm input resistor (R1) and delivers a DC current gain (hFE) ranging from 100 to 600 at 1 mA and 5 V. Packaged in the compact SOT-323 (UMT3F) surface-mount format, it dissipates up to 200 mW and functions reliably within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates an NPN transistor with a 10 kOhm base resistor to reduce component count and board space.
- Provides high current gain stability suitable for switching applications requiring consistent output characteristics.
- Utilizes a small-footprint SOT-323 package designed for automated surface-mount assembly processes.
Applications
- General-purpose signal switching in consumer electronics
- Driver circuits for low-power loads in portable devices
- Logic level translation interfaces in embedded systems
Procurement Notes
Verify the complete ordering part number against official ROHM documentation to ensure correct suffix alignment. Confirm that the specific tape-and-reel quantity matches project requirements. Check for any regional compliance certifications required for the target market. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet prior to soldering.
Selection Notes
Select this component when a compact NPN switch with integrated biasing is required. Compare power dissipation ratings against thermal constraints in the final enclosure. Evaluate the hFE range to ensure adequate drive capability for the intended load. Verify compatibility with existing PCB footprint standards for the SOT-323 package.
Part Context
This part belongs to the DTC114 series of digital transistors, which are standard products developed by ROHM Semiconductor. The series is designed for general-purpose use but is explicitly not recommended for automotive equipment. The TUBTL variant specifically denotes the SOT-323 package configuration with a standard taping reel quantity.
Replacement Considerations
The DTC114TU3HZGT106 is listed as a similar level replacement with the same pinout and package. Both parts share identical polarity and supply voltage specifications. Verify that the replacement meets all thermal and current requirements before implementation.
