DMC5640M0R

Overview

The Panasonic DMC5640M0R is a dual NPN digital transistor array housed in an SMini6 package. It integrates two pre-biased NPN transistors with internal base resistors, rated for a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device features a low saturation voltage and a current gain ratio of 0.047, designed to simplify circuit design by reducing external component count.

Feature Summary

• Integrates dual NPN transistors with built-in base resistors for simplified switching applications
• Provides high-speed switching capabilities with low saturation voltage characteristics
• Reduces printed circuit board space requirements through compact surface-mount packaging

Applications

• General-purpose signal switching circuits
• Driver stages for logic gates and microcontrollers
• Battery protection circuits requiring fast response times

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required resistance values and package variants. Confirm lifecycle status as components may be obsolete or subject to last-time buys. Cross-reference pinout diagrams with target PCB footprints to prevent installation errors during assembly processes.

Selection Notes

Select this component when dual independent switching channels are required within a minimal footprint. Evaluate the internal base resistor value against the driving source impedance to ensure adequate turn-on speed. Consider the thermal dissipation limits of the SMini6 package under continuous load conditions for reliable long-term operation.

Part Context

This part belongs to Panasonic's series of pre-biased bipolar junction transistor arrays. These devices combine discrete transistors with integrated biasing networks to replace multiple individual components. The SMini6 package offers a compact solution for consumer electronics and industrial control systems where space efficiency is critical.
