Overview
The DDTC123EUA-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, housed in a SOT-323 package. It features built-in biasing resistors with nominal values of R1 = 2.2 kΩ and R2 = 2.2 kΩ. The device supports a supply voltage (VCC) of 50 V and a continuous collector current (IO) of 100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 20 at 20 mA, a typical transition frequency (fT) of 250 MHz, and a power dissipation rating of 200 mW. Operating temperature ranges from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for high reliability
- Integrated biasing resistors (R1 = R2) simplify circuit design
- Qualified to AEC-Q101 standards for automotive applications
- Fully RoHS compliant and halogen-free green device
Applications
- Automotive electronic systems requiring AEC-Q101 qualification
- General-purpose switching and amplification circuits
- Driver circuits for low-power loads
Procurement Notes
Verify the complete part number suffix, specifically '-7-F', against official documentation to confirm packaging details such as reel size and tape width. Confirm RoHS compliance status and ensure the component meets specific environmental requirements like halogen-free specifications before procurement.
Selection Notes
Select this component when a single NPN pre-biased transistor with equal base and emitter resistors is required. Ensure the application operates within the 50 V supply limit and 100 mA current capacity. Verify that the SOT-323 package dimensions fit the PCB layout constraints and that the thermal resistance allows for adequate heat dissipation at 200 mW.
Part Context
This component belongs to the DDTC (R1 = R2 Series) UA family from Diodes Incorporated. It is designed as a complementary counterpart to PNP types like the DDTA series. The 'EUA' designation indicates specific resistor values and the SOT-323 package type within this product line.
Replacement Considerations
Direct substitutes within the same manufacturer's lineup include other variants in the DDTC123EUA series if different resistor tolerances are acceptable. Cross-manufacturer replacements must match the NPN polarity, SOT-323 package, 50V/100mA ratings, and integrated resistor configuration.
