DDTC114WUA-7

Overview

The DDTC114WUA-7-F is a single NPN pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT-323 surface-mount package. It features built-in biasing resistors with nominal values of R1 = 10 kΩ and R2 = 4.7 kΩ. The device supports a maximum supply voltage (VCC) of 50 V and a continuous collector current (IOUT) of 100 mA. Power dissipation is rated at 200 mW, with a thermal resistance (RθJA) of 625 °C/W. The DC current gain (Gl) is specified at a minimum of 24 under standard test conditions. Operating and storage temperatures range from -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors simplify circuit design
• Surface mount package optimized for automated assembly

Applications

• Switching applications requiring integrated base drive
• Driver circuits for logic-to-power level translation
• General-purpose digital switching in consumer electronics

Procurement Notes

Verify the complete part number includes the suffix '-7-F' to ensure compliance with RoHS 3 directives and halogen-free specifications. Confirm that the ordering quantity aligns with the manufacturer's standard packing quantity of 3,000 units per reel. Check for specific automotive qualification requirements if the application demands AEC-Q100/101 standards or IATF 16949 manufacturing facilities.

Selection Notes

Select this component when a compact NPN solution with asymmetric biasing ratios is required. The 10kΩ input resistor provides moderate drive capability, while the 4.7kΩ emitter resistor sets the specific gain characteristics. Ensure the PCB layout accommodates the SOT-323 footprint dimensions and adheres to the recommended pad layout for optimal thermal dissipation.

Part Context

This component belongs to the DDTC (R1≠R2 Series) UA family, which offers various combinations of internal resistors within the SOT-323 package. Unlike symmetric variants, this model provides distinct R1 and R2 values to tailor the input impedance and gain ratio for specific interface requirements.

Replacement Considerations

Direct pin-compatible replacements include other Diodes Incorporated models from the same series such as DDTC114YUA-7-F or DDTC124XUA-7-F, provided their specific resistor ratios match the circuit design constraints.
