DMC5640L0R

Overview

The DMC5640L0R is a pre-biased dual NPN transistor manufactured by Panasonic Electronic Components. It features a collector-emitter voltage (Vceo) of 50V and a continuous collector current of 100mA. The device includes integrated base resistors with a value of 4.7 kOhms, designed to simplify circuit design for switching and amplification applications. It is housed in an SMini6-F3-B surface-mount package, offering a compact footprint suitable for space-constrained electronic designs.

Feature Summary

• Dual NPN configuration with integrated pre-biasing for simplified drive circuits
• Compact SMini6-F3-B surface-mount package for high-density PCB layouts
• Integrated base resistors eliminate external component requirements

Applications

• General-purpose switching circuits
• Amplification stages in compact electronics
• Driver circuits for low-power loads

Procurement Notes

Verify the specific ordering suffix and packaging type when sourcing. Confirm that the received components match the Panasonic Electronic Components part number DMC5640L0R. Ensure compatibility with the intended operating temperature range and electrical parameters before integration into the final assembly.

Selection Notes

Select this component for applications requiring a dual NPN transistor with built-in biasing resistors. The 50V rating and 100mA current capacity suit low-to-medium power switching tasks. The SMini6 package is appropriate where board space is limited. Verify that the internal resistor values meet the specific drive requirements of the target circuit.

Part Context

This component belongs to Panasonic's series of digital transistors, which integrate resistors directly onto the silicon die. These devices replace discrete resistor-transistor networks, reducing component count and assembly time. The DMC5640L0R specifically provides a dual NPN solution within a small outline package format.

Replacement Considerations

Consult official Panasonic documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other manufacturers' dual NPN pre-biased transistors without verifying pinout, electrical ratings, and package dimensions.
