DDTC124TE-7

Overview

The DDTC124TE-7-F is an NPN pre-biased small signal transistor manufactured by Diodes Incorporated. It features a built-in biasing resistor (R1) with a nominal value of 22 kΩ, housed in a SOT523 surface-mount package. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Key electrical characteristics include a DC current transfer ratio (hFE) ranging from 100 to 600 at IC = 1mA and VCE = 5V, and a gain-bandwidth product (fT) of 250 MHz. Power dissipation is rated at 150 mW, with an operating temperature range spanning -55°C to +150°C.

Feature Summary

Epitaxial planar die construction for reliable performance
Built-in single biasing resistor (R1 only) simplifies circuit design
AEC-Q101 qualified and PPAP capable for automotive applications
Totally lead-free, halogen-free, and antimony-free compliant

Applications

Automotive interface driving circuits
General-purpose switching applications
Inverter control logic

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status. Standard versions are marked 'Standard', while automotive-grade variants carry the 'Q' suffix. Confirm that the component meets RoHS 3 directives and IATF 16949 manufacturing requirements if intended for regulated automotive supply chains.

Selection Notes

Select this component when a single NPN digital transistor with a 22 kΩ base resistor is required. Ensure the application voltage does not exceed the 50 V collector-emitter rating. Verify thermal management capabilities, as power dissipation is limited to 150 mW in standard mounting conditions. Consider the complementary PNP type if negative logic or pull-down configurations are needed.

Part Context

This part belongs to the DDTC (R1-ONLY SERIES) E family, which integrates a single biasing resistor into an NPN transistor structure. It serves as a simplified alternative to discrete resistor-transistor networks, reducing board space and assembly complexity. The series includes various resistance values to accommodate different drive requirements.

Replacement Considerations

Direct substitutes within the same manufacturer's portfolio include other members of the DDTC R1-only series, such as DDTC114TE-7-F (10 kΩ) or DDTC144TE-7-F (47 kΩ), provided the resistance value matches the design intent. Complementary PNP equivalents are available in the DDTA series.
