Overview
The DDTC123JUA-7-F is a single NPN pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT-323 surface-mount package. It integrates built-in biasing resistors with nominal values of R1 = 2.2 kΩ and R2 = 47 kΩ. The device supports a supply voltage (VCC) of 50 V and a continuous collector current (IC) of 100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 80 at VOUT = 5 V and IOUT = 10 mA, and a transition frequency (fT) of 250 MHz. Power dissipation is rated at 200 mW, with an operating temperature 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
- Lead-free and fully RoHS compliant manufacturing
Applications
- General-purpose switching applications
- Driver circuits for low-power loads
- Logic level translation interfaces
Procurement Notes
Verify the complete part number against official documentation, as suffixes such as '-7-F' define specific packaging configurations like reel quantities. Confirm compliance requirements including RoHS and halogen-free status directly with the manufacturer or authorized distributors before procurement. Ensure the ordering suffix matches the required tape and reel specifications for your assembly line equipment.
Selection Notes
Select this component when a compact NPN solution with integrated base and emitter resistors is required. The specific resistor ratio of approximately 0.047 determines the input drive characteristics and saturation behavior. Verify that the 2.2 kΩ base resistor value aligns with the driving source impedance and desired switching speed for the target application environment.
Part Context
This component belongs to the DDTC123 series of pre-biased transistors from Diodes Incorporated. The 'UA' suffix indicates the SOT-323 package type, while the 'J' designation specifies the unique internal resistor network configuration within the family. It serves as a discrete alternative to complex driver stages in space-constrained designs.
Replacement Considerations
Direct substitutes within the same series include DDTC123YUA-7-F, which shares the SOT-323 package but features different resistor values (R1=2.2kΩ, R2=10kΩ). Any replacement must be evaluated for electrical compatibility regarding input resistance ratios and current gain specifications.
