Overview
The DDTC114GUA-7 is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and a built-in biasing resistor (R2) with a nominal value of 10 kΩ. The device is housed in a SOT-323 package, measuring approximately 1.35 mm x 2.20 mm x 0.40 mm. Key electrical ratings include a collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and power dissipation of 200 mW at 25°C. The DC current transfer ratio (hFE) has a minimum value of 30 at IC = 5 mA and VCE = 5 V. The operating temperature range spans from -55°C to +150°C.
Feature Summary
- Integrates a single internal bleeder resistor (R2) for simplified circuit design
- Utilizes epitaxial planar die construction for reliable performance
- Compliant with RoHS standards and lead-free plating specifications
Applications
- Switching applications requiring integrated base biasing
- Driver circuits for low-power loads
- General-purpose digital logic interfacing
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The standard tape and reel quantity is 3000 units per reel. Ensure compliance with moisture sensitivity level 1 requirements during storage and handling. Confirm that the component meets the required environmental standards for the intended application environment.
Selection Notes
Select this component when a single NPN pre-biased transistor with an R2-only configuration is required. The 10 kΩ internal resistor value suits applications needing moderate base drive isolation. Consider the SOT-323 package dimensions for space-constrained PCB layouts. Verify thermal resistance characteristics if high ambient temperatures are expected.
Part Context
This part belongs to the DDTC (R2-ONLY SERIES) UA family from Diodes Incorporated. It is specifically designed as an NPN pre-biased transistor variant within this series. Other members of the series include different resistor values such as the DDTC124GUA and DDTC144GUA, offering flexibility in biasing configurations while maintaining the same physical footprint and electrical characteristics.
Replacement Considerations
Cross-reference with other manufacturers' NPN pre-biased transistors in the SOT-323 package. Verify pinout compatibility and electrical parameters such as VCEO, IC, and hFE before substitution. Ensure the replacement component supports the required operating temperature range and power dissipation limits.
