Overview
The DTC114TU3T106 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323-3 (UMT3) surface-mount package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. The device features a typical input resistance of 10 kOhms with a resistor ratio of 0.47. Minimum DC current gain (hfe) is specified as 100 at -1 mA and -5 V. Maximum operating frequency reaches 250 MHz, with power dissipation rated at 200 mW and a maximum operating temperature of +150 C.
Feature Summary
- Integrates built-in bias resistors to enable inverter circuit configuration without external input components.
- Simplifies circuit design by requiring only on/off condition settings for operation.
- Provides complementary PNP type options within the series.
Applications
- Inverter circuits
- Driver circuits
- Switching applications
Procurement Notes
Verify component authenticity through authorized ROHM Semiconductor distributors or certified suppliers. Confirm RoHS compliance status via official documentation. Ensure storage conditions adhere to moisture sensitivity level requirements. Validate part markings against manufacturer specifications to prevent counterfeit introduction into supply chains.
Selection Notes
Select this PNP variant when negative logic inversion or high-side switching is required. Compare hfe minimums and resistor ratios against NPN alternatives like DTC114GU3T106 if positive polarity is needed. Verify that the 50 V rating and 100 mA current capacity meet specific load requirements. Check thermal dissipation limits for high-density PCB layouts.
Part Context
This component belongs to the DTC114TUA series of Bias Resistor Built-in Transistors (BRBTs). It shares the UMT3 package form factor with other variants such as DTC114TUAT106. The series offers standardized integration of base and emitter resistors to reduce board space and assembly complexity compared to discrete transistor solutions.
