DDTC143XKA-7-F

Overview

The DDTC143XKA-7-F is a single NPN digital transistor manufactured by Diodes Incorporated, housed in an SOT-323 (SC-70) surface-mount package. It integrates a built-in bias resistor network with typical values of 4.7 kOhms and 10 kOhms, yielding a resistor ratio of 0.47. The device supports a continuous collector current of 100 mA and a peak DC collector current of 100 mA, with a minimum DC current gain (hFE) of 30. It operates within a temperature range of -55°C to +150°C and features a power dissipation rating of 200 mW.

Feature Summary

• Integrates a single NPN transistor with a built-in bias resistor network for simplified circuit design.

Applications

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets required environmental standards and operating temperature ranges for the target application before integration into production designs.

Selection Notes

Select this component when a compact NPN digital transistor with a 4.7k/10k resistor ratio is required. Confirm that the SOT-323 package dimensions fit the PCB layout constraints and that the 100mA current rating satisfies the load requirements.

Part Context
