DDTC114YUA-7-F

Overview

The DDTC114YUA-7-F is a pre-biased NPN transistor from Diodes Incorporated, housed in an SOT323 surface-mount package. It integrates internal biasing resistors with nominal values of R1 = 10 kΩ and R2 = 47 kΩ. The device supports a maximum supply voltage (VCC) of 50 V and a continuous collector current (IOUT) of 100 mA. Key electrical characteristics include a DC current gain (Gl) of 68 at VOUT = 5 V and IOUT = 5 mA, and a transition frequency (fT) of 250 MHz. Power dissipation is rated at 200 mW, with an operating temperature range spanning -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors eliminate external resistor requirements
• Surface mount package optimized for automated assembly processes
• Fully RoHS compliant and halogen-free green device

Applications

• General-purpose switching applications
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the complete part number including the suffix against official Diodes Incorporated documentation before ordering. Confirm that the specific reel size and tape width match your automated pick-and-place equipment specifications. Ensure compliance with local environmental regulations regarding lead-free and halogen-free components during procurement.

Selection Notes

Select this component when a compact NPN solution with fixed bias ratios is required. The 10kΩ/47kΩ resistor combination suits applications needing moderate input drive currents. Verify that the 100mA output current capability meets load requirements and that the SOT323 thermal resistance allows adequate heat dissipation within the target operating temperature range.

Part Context

This part belongs to the DDTC series of pre-biased transistors featuring unequal internal resistors (R1≠R2). It serves as a complement to other variants in the UA package family, offering specific gain and input impedance characteristics tailored for distinct logic interface needs within Diodes Incorporated's discrete semiconductor portfolio.

Replacement Considerations

Direct substitutes within the same manufacturer family include DDTC114WUA-7-F, which shares the SOT323 package but utilizes different internal resistor values (R1=10kΩ, R2=4.7kΩ). Cross-manufacturer replacements require matching the NPN configuration, 50V rating, 100mA current limit, and SOT323 footprint while verifying equivalent electrical parameters.
