DDTC143ECA-TP

Overview

The DDTC143ECA-TP is a digital transistor manufactured by Micro Commercial Components (MCC). It is an NPN type device housed in an SOT-23 surface-mount package. The component integrates built-in biasing resistors, specifically configured with two resistors (R1 and R2) to facilitate switching applications. It operates within a maximum power dissipation of 200 mW and supports a maximum operating temperature of +150°C. The device features a transition frequency of 250 MHz and a minimum DC current gain (hFE) of 30 at specified test conditions.

Feature Summary

• Integrates dual biasing resistors for simplified circuit design
• NPN polarity configuration for standard switching logic
• Compact SOT-23 surface-mount packaging

Applications

• General-purpose digital switching circuits
• Interface driving between logic families
• High-frequency signal processing up to 250 MHz

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm pinout and electrical characteristics. Ensure compatibility with RoHS3 standards if required by the target assembly process. Cross-reference datasheet revision dates to account for potential manufacturing updates or packaging changes that may affect footprint or material composition during procurement.

Selection Notes

Select this component when a pre-biased NPN transistor with dual resistors is required. Compare the 200 mW power rating and 50 V breakdown voltage against circuit load requirements. Verify that the SOT-23 package fits the available PCB real estate. Consider the 250 MHz frequency limit for high-speed applications to ensure adequate performance margins.

Part Context

This part belongs to the DTC143 series of digital transistors from Micro Commercial Components. It shares the same core transistor structure as the DTC143ECA-TP but differs in internal resistor configuration. The series is designed to replace discrete resistor networks, reducing board space and assembly complexity in modern electronic devices requiring reliable NPN switching elements.

Replacement Considerations

Direct substitutes include the DTC143ECA-TP from the same manufacturer family. Other compatible parts must match the NPN polarity, SOT-23 package, and integrated dual-resistor topology. Verify equivalent electrical ratings for voltage, current, and frequency before substitution.
