DRC3143T0L

Overview

The Panasonic DRC3143T0L is an NPN digital transistor housed in the SSSMini3 F2 B surface-mount package. It features a maximum collector-emitter voltage of 50 V and a maximum power dissipation of 100 mW. The device includes a built-in typical input resistor of 4.7 kΩ, facilitating direct logic interface without external components. Designed for single-transistor configuration with three pins, it supports a maximum operating temperature of +150 °C. Its compact physical dimensions are 1.2 x 0.8 x 0.47 mm, making it suitable for high-density circuit board layouts.

Feature Summary

• Integrated internal base resistor eliminates the need for external biasing components
• High thermal stability supporting operation up to +150 °C
• Compact footprint designed for automated surface-mount assembly

Applications

• Logic level shifting between microcontrollers and peripheral devices
• Switching applications in portable electronic equipment
• Interface circuits in automotive control modules

Procurement Notes

Verify the specific suffix 'T0L' against official Panasonic datasheets to confirm reel packaging specifications and tape-and-reel dimensions. Ensure that the ordering code matches the required quantity per reel for your production line setup. Cross-reference the component marking with the manufacturer's latest identification guide to prevent counterfeit substitution during incoming inspection.

Selection Notes

Select this component when a compact NPN switch with integrated base resistance is required. The 4.7 kΩ internal resistor value determines the input current requirements from the driving logic source. Consider the 100 mW power dissipation limit relative to the ambient temperature and PCB copper area available for heat spreading during continuous operation.

Part Context

This part belongs to the Panasonic DRC series of digital transistors, which combine bipolar junction transistors with on-chip resistors. The SSSMini3 package is part of Panasonic's lineup for miniaturized semiconductor solutions, offering a balance between electrical performance and space efficiency for modern consumer and industrial electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters such as Vce(sat) and hFE before considering any alternative manufacturers or generic equivalents.
