DDTC124EE-7-F

Overview

The DDTC124EE-7-F is an NPN pre-biased transistor manufactured by Diodes Incorporated, housed in a surface-mount SOT523 package. It features built-in biasing resistors with nominal values of R1 = 22 kΩ and R2 = 22 kΩ. The device supports a maximum 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 56 at 5 mA output current, a transition frequency (fT) of 250 MHz, and a power dissipation rating of 150 mW. Operating temperature ranges from -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors simplify circuit design
• Lead-free and fully RoHS compliant manufacturing
• Halogen and antimony-free green device composition

Applications

• Interface driving circuits
• Inverter applications
• General-purpose switching

Procurement Notes

Verify the complete part number including the suffix '-7-F' to confirm standard reel packaging containing 3000 units per 7-inch reel. Confirm compliance requirements such as RoHS 3 and halogen-free status against specific project needs. Ensure the ordering information matches the required resistor tolerance and marking codes provided in the manufacturer's documentation.

Selection Notes

Select this component when a single NPN transistor with equal base and emitter resistors is required. The 22kΩ internal resistance ratio suits moderate drive applications. Verify that the 150mW power dissipation limit and 50V breakdown voltage meet the system's electrical constraints. Consider the SOT523 footprint dimensions during PCB layout planning.

Part Context

This component belongs to the DDTC (R1 = R2 Series) EE family from Diodes Incorporated. It serves as the NPN counterpart to the DDTA series PNP devices. The 'EE' designation indicates the specific SOT523 package variant. This series provides integrated biasing solutions to reduce external component count in digital switching applications.

Replacement Considerations

Direct substitutes within the same series include DDTC123EE-7-F (2.2kΩ), DDTC143EE-7-F (4.7kΩ), DDTC114EE-7-F (10kΩ), DDTC144EE-7-F (47kΩ), and DDTC115EE-7-F (100kΩ). Complementary PNP versions are available in the DDTA124EE-7-F configuration.
