DMC266010R

Overview

The Panasonic DMC266010R is a dual NPN digital transistor array featuring built-in bias resistors, designed for surface-mount applications in the Mini6-G4-B package. It provides a collector-emitter breakdown voltage of 50V and a maximum continuous collector current of 100mA. The device incorporates two 10 kΩ base resistors (R1) and two 10 kΩ emitter resistors (R2). Key electrical characteristics include a DC current gain (hFE) of at least 35 at 5mA collector current and 10V, with a maximum saturation voltage of 250mV at 500µA base current and 10mA collector current. The unit supports a maximum power dissipation of 300mW.

Feature Summary

• Integrated dual NPN configuration with pre-biased resistors to simplify circuit design
• Compact Mini6-G4-B surface mount package suitable for space-constrained layouts
• High input impedance via 10 kΩ internal base resistors reducing drive current requirements

Applications

• General-purpose switching circuits requiring compact dual-transistor solutions
• Interface drivers for logic level translation between microcontrollers and loads
• Low-power signal amplification stages in consumer electronics

Procurement Notes

Verify component authenticity through authorized distributors as this part is obsolete. Check for RoHS compliance status on available surplus stock. Ensure storage conditions prevent moisture sensitivity damage prior to reflow soldering. Confirm package marking matches official datasheet specifications to avoid counterfeit substitution.

Selection Notes

Select this component when a dual NPN digital transistor with 50V rating and 100mA capacity is required in a Mini6 package. Compare hFE and Vce(sat) specifications against alternative obsolete parts if direct replacement is unavailable. Consider thermal derating for 300mW dissipation in enclosed environments.

Part Context

This component belongs to Panasonic's DMC26 series of digital transistors. It serves as a legacy solution for integrated bias resistor arrays. The Mini6-G4-B package offers a small footprint compared to discrete dual-transistor implementations. It was commonly used in portable devices before newer packaging technologies became standard.

Replacement Considerations

Public confirmed substitute part numbers are not available in verified sources. The DMC261010R shares similar electrical characteristics but uses a different Mini5-G3-B package. Verify pin compatibility and thermal performance before substituting with other dual NPN digital transistors from manufacturers like Toshiba or Nexperia.
