DRC2144T0L

Overview

The Panasonic DRC2144T0L is an NPN digital transistor featuring a built-in bias resistor, housed in the Mini3 G3 B surface-mount package. It supports a maximum DC collector current of 100 mA and a collector-emitter voltage rating of 50 V. The device dissipates up to 200 mW of power and operates at temperatures reaching +150 °C. Its typical input resistance is 47 kΩ, facilitating direct interface with logic circuits. The component measures 2.9 x 1.5 x 1.1 mm and contains a single transistor element within a three-terminal configuration.

Feature Summary

• Integrates a pre-biased resistor network to simplify circuit design and reduce board space requirements.
• Provides high thermal stability with a maximum operating temperature of +150 °C for robust performance.
• Utilizes a compact Mini3 G3 B surface-mount package suitable for dense PCB layouts.

Applications

• Logic level shifting between microcontrollers and peripheral devices
• Switching applications in consumer electronics and office automation equipment
• Signal buffering and driver stages in communication equipment

Procurement Notes

Verify the specific ordering suffix against official Panasonic Industry documentation to ensure correct packaging and tape specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Cross-reference part numbers carefully as suffixes may indicate variations in reel size or shipping quantity rather than electrical function.

Selection Notes

Select this component when a compact NPN switching solution with integrated base resistance is required. Ensure the 47 kΩ internal resistor aligns with the driving source's current capabilities. Verify that the 50 V collector-emitter voltage and 100 mA current ratings exceed the application's peak operational demands. Consider the Mini3 G3 B footprint constraints during the PCB layout phase.

Part Context

This component belongs to the Panasonic DRC series of digital transistors, which are designed to replace discrete resistor-transistor combinations. The series offers standardized electrical characteristics across various packages, including the Mini3 G3 B format used here. These devices are commonly utilized in industrial and consumer electronics where space efficiency and simplified biasing are critical design factors.

Replacement Considerations

The DRC2144T0L serves as a direct substitute for the Rohm Semiconductor DTC144TCAT116. Both parts share identical NPN configurations, 50 V ratings, 100 mA currents, and 47 kΩ base resistors. Verify pinout compatibility and physical dimensions before finalizing any replacement strategy.
