DDTC114YKA-7-F

Overview

The DDTC114YKA-7-F is a digital transistor manufactured by Diodes Incorporated, classified as a pre-biased NPN single configuration device. It integrates an internal bias resistor network to simplify circuit design and reduce component count. The unit operates with a maximum collector-emitter voltage of 50 V and supports a continuous collector current of 100 mA. It features a typical input resistance of 10 kOhms and a minimum DC current gain (hFE) of 100. The device is housed in a compact SOT-23-3 surface-mount package, suitable for space-constrained applications. It functions within a temperature range from -55 °C to +150 °C and has a power dissipation rating of 200 mW.

Feature Summary

• Integrates built-in bias resistors to eliminate external components and simplify PCB layout.
• Provides high DC current gain for efficient switching performance in digital logic circuits.
• Utilizes a compact SOT-23-3 surface-mount package for automated assembly and space efficiency.

Applications

• General-purpose switching in digital logic interfaces
• Driver circuits for low-power loads
• Level shifting between different voltage domains

Procurement Notes

Verify the specific suffix 'KA' against the manufacturer's official datasheet to confirm pinout and electrical tolerances, as suffixes often denote specific tape-and-reel packaging or regional compliance variations. Ensure the source document explicitly lists this exact part number to avoid confusion with similar variants like DDTC114TCA-7-F. Cross-reference RoHS status and moisture sensitivity levels directly from the certified data sheet provided by Diodes Incorporated.

Selection Notes

Select this component when a single NPN digital transistor with a 10 kOhm base resistor is required. Compare the 100 mA collector current and 50 V breakdown voltage against circuit requirements. Consider the SOT-23-3 package dimensions for board space constraints. Verify that the 200 mW power dissipation rating meets thermal management needs in the target application environment.
