DMC261040R

Overview

The DMC261040R is a composite digital transistor manufactured by Panasonic Industry, featuring an integrated dual NPN configuration within a Mini5-G3-B surface-mount package. This component integrates internal base resistors to simplify circuit design and reduce board space. Key electrical specifications include a collector-emitter maximum voltage (VCEO) of 50 V and a continuous collector current rating of 100 mA. The typical input resistance is specified at 47 kOhms. Designed for high-temperature environments, the device supports a maximum operating temperature of +150°C. It is supplied in reel, cut tape, or MouseReel formats.

Feature Summary

• Integrates dual NPN transistors with built-in base resistors for simplified switching applications
• Compact Mini5-G3-B SMD/SMT footprint optimizes PCB real estate
• High thermal stability supporting operation up to +150°C

Applications

• General-purpose signal switching circuits
• Driver circuits for low-current loads
• Logic level translation interfaces

Procurement Notes

Verify availability status carefully as this component may be subject to discontinuation. Confirm RoHS compliance details through official Panasonic documentation prior to integration. Ensure the specific ordering suffix matches the required packaging format, such as Reel or Cut Tape, as these do not alter the electrical function but affect handling procedures.

Selection Notes

Select this component when a compact dual NPN solution with integrated biasing is required. Verify that the 50 V VCEO and 100 mA Ic ratings exceed the maximum circuit demands. Consider the 47 kOhm typical input resistance for base drive calculations. Ensure the design accommodates the +150°C maximum junction temperature limit under all operating conditions.

Part Context

The DMC261040R belongs to Panasonic's DMC series of composite digital transistors. These devices are designed to replace discrete resistor-transistor networks, offering improved reliability and reduced assembly costs. The Dual NPN configuration allows for complementary switching functions within a single small outline package, commonly used in consumer electronics and industrial control boards.

Replacement Considerations

Consult Panasonic Industry's official cross-reference guides for verified substitute part numbers. Do not assume functional equivalence with generic dual NPN digital transistors without verifying pinout compatibility, VCEO ratings, and package dimensions against the Mini5-G3-B specification.
