DDTC143EUA-TP

Overview

The DDTC143EUA-TP is an NPN digital transistor array manufactured by Micro Commercial Components (MCC). It integrates a single NPN transistor with two built-in bias resistors, R1 and R2, both specified at 4.7 kOhms. The device features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 500 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 30 at 10 mA and 5 V, a maximum saturation voltage of 300 mV at 500 µA base and 10 mA collector current, and a transition frequency of 160 MHz. Power dissipation is rated at 200 mW, and the component is housed in a surface-mount SOT-323 package.

Feature Summary

• Integrates an NPN transistor with dual 4.7 kOhm bias resistors for simplified circuit design.
• Provides high-speed switching capability with a 160 MHz transition frequency.
• Supports moderate load currents up to 500 mA with low saturation voltage.

Applications

• General-purpose switching applications in consumer electronics.
• Driver circuits for small loads requiring pre-biased control.
• Logic level translation and interface buffering in embedded systems.

Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official MCC documentation to ensure correct component identification. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Check for any recent production change notices that may affect packaging or assembly specifications.

Selection Notes

Select this component when an NPN digital transistor with equal internal resistor values is required. Ensure the 500 mA collector current and 200 mW power dissipation ratings meet the application's thermal and electrical demands. Verify that the SOT-323 footprint aligns with the PCB layout constraints.

Part Context

This component belongs to the DTC143 series of digital transistors from Micro Commercial Components. It is distinct from similar models like the DTC143ECA-TP by its specific SOT-323 packaging and integrated resistor configuration. The series offers various configurations for different biasing needs in compact surface-mount designs.
