DMC266060R

Overview

The Panasonic DMC266060R is a dual NPN pre-biased bipolar junction transistor array housed in a Mini6-G4-B surface-mount package. It features an integrated 4.7 kΩ base resistor for each transistor, simplifying circuit design by reducing component count and board space. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA per element. With a total power dissipation rating of 300mW, it is suitable for low-power switching applications. The unit offers a DC current gain of at least 160 at 5mA collector current and maintains a saturation voltage of no more than 250mV under specified conditions.

Feature Summary

• Integrated dual NPN configuration with built-in base resistors to streamline driver circuit implementation
• Compact Mini6-G4-B surface-mount footprint designed for high-density PCB layouts
• Optimized for low-voltage switching operations with defined saturation characteristics

Applications

• General-purpose signal switching in consumer electronics
• Driver circuits for low-current loads in industrial control modules
• Logic level translation interfaces in embedded systems

Procurement Notes

This component has been officially declared obsolete by the manufacturer as of May 9, 2019. Verification of availability should focus on surplus distributors or authorized secondary markets rather than direct manufacturing channels. Buyers must confirm the authenticity of stock through rigorous documentation checks due to the end-of-life status. Cross-referencing with qualified replacement parts is recommended for new designs to ensure long-term supply chain stability and compliance with current procurement standards.

Selection Notes

Designers should evaluate the 50V breakdown voltage and 100mA current limits against peak operational demands to prevent overstress. The fixed 4.7 kΩ internal resistor value dictates the input drive requirements; verify that the upstream logic can source sufficient current to achieve full saturation without excessive delay. Thermal management must account for the 300mW total power dissipation limit within the Mini6-G4-B package constraints during continuous operation.

Part Context

The DMC266060R belongs to the DMC26606 series of pre-biased transistor arrays manufactured by Panasonic Industry. This series integrates passive components directly onto the semiconductor die to enhance reliability and reduce assembly complexity. As a discontinued item, it represents a legacy solution for compact switching applications where space efficiency was prioritized over modular customization.

Replacement Considerations
