Overview
The DTC114YUAT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in a SOT-323 (UMT3) surface-mount package. It integrates bias resistors with an input resistance of 10 kOhms and an emitter-base resistance of 47 kOhms, yielding a typical resistor ratio of 4.7. The device supports a collector-emitter voltage of 50 V and a continuous collector current of 100 mA, with a maximum power dissipation of 200 mW. Key electrical characteristics include a minimum DC current gain of 68 at 5 mA/5 V, a saturation voltage of 300 mV, and a transition frequency of 250 MHz. It operates within a temperature range up to +150°C.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Provides high-speed switching capabilities suitable for applications requiring fast response times.
- Features low saturation voltage for efficient power consumption during on-state operation.
Applications
- General-purpose switching circuits in consumer electronics.
- Driver stages for relays, solenoids, and small motors.
- Logic level shifting and buffer interfaces in digital systems.
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and tape specifications. Confirm RoHS compliance status and automotive qualification requirements if applicable to the target application environment before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN digital transistor with a 10 kOhm base resistor is required. Ensure the 50 V collector-emitter voltage rating exceeds the maximum circuit voltage. Verify that the 100 mA collector current capability meets the load requirements and that the SOT-323 package fits the available PCB footprint constraints.
Part Context
This part belongs to the ROHM DTC114 series of pre-biased transistors. It shares pinout compatibility with other variants in the family, such as the DTC114YU3T106, while differing in internal resistor ratios and specific electrical parameters. The UMAT suffix indicates the specific taping configuration for automated assembly processes.
Replacement Considerations
The DTC114YU3T106 is a confirmed substitute with the same pinout and package. Verify that the alternative part's resistor values and gain characteristics align with the original design specifications before implementation.
