Overview
The DTC114YU3T106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates bias resistors with a typical base resistance (R1) of 10 kOhms and emitter-base resistance (R2) of 47 kOhms. The device supports a collector continuous current of 100 mA and a collector-emitter voltage (VCEO) of 50 V. Key electrical parameters include a minimum DC current gain (hfe) of 68 at 5 mA/5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 200 mW. The saturation voltage is specified at 300 mV under defined conditions.
Feature Summary
- Integrates built-in bias resistors to eliminate external resistor requirements for inverter circuit configurations.
- Provides high-speed switching capabilities suitable for applications requiring operation up to 250 MHz.
- Features a compact SOT-323 footprint designed for space-constrained surface-mount assembly.
Applications
- Inverter circuits utilizing integrated biasing
- General-purpose switching applications
- Driver circuits for low-current loads
Procurement Notes
Verify the specific suffix T106 against the manufacturer's latest datasheet to confirm packaging details and revision status. Ensure compatibility with RoHS3 regulations if required by the target application. Cross-reference the Mouser part number 755-DTC114YU3T106 or DigiKey identifier DTC114YU3T106TR-ND for accurate sourcing channels and lead times.
Selection Notes
Select this component when a single NPN configuration with a 10 kOhm input resistance is required. The 50 V collector-emitter voltage rating distinguishes it from lower-voltage variants like the DTC114W series. Consider the 200 mW power dissipation limit for thermal management in dense PCB layouts compared to higher-power packages.
Part Context
This component belongs to the DTC114 family of pre-biased transistors. It shares the same physical package and general topology as variants such as DTC114GU3T106 and DTC114EU3T106, differing primarily in internal resistor ratios and voltage ratings. The UMT3 designation refers to the specific SC-70/SOT-323 form factor used across this product line.
Replacement Considerations
Direct substitutes within the same package and polarity include DTC114GU3T106 and DTC114EU3T106. Verify that the replacement part meets the specific 10 kOhm input resistance requirement, as other family members may utilize different resistor values or ratios.
