DMC564050R

Overview

The DMC564050R is a dual NPN pre-biased transistor manufactured by Panasonic Electronic Components. It features an integrated base resistor of 10k ohms and operates with a maximum collector-emitter breakdown voltage of 50V. The device supports a continuous collector current of 100mA and dissipates up to 150mW of power. Key electrical characteristics include a minimum DC current gain (hFE) of 160 at 5mA and 10V, and a maximum collector-emitter saturation voltage of 250mV at 500µA base current and 10mA collector current. The component is housed in an SMini6-F3-B surface-mount package.

Feature Summary

• Integrates two NPN transistors with a single 10k ohm base resistor for simplified circuit design
• Provides high current gain performance suitable for switching applications
• Offers low saturation voltage to minimize power loss during operation

Applications

• General-purpose signal switching circuits
• Driver stages for small loads
• Logic interface buffering

Procurement Notes

Verify the specific manufacturer datasheet to confirm the active status of this component, as some distributors list it as discontinued. Ensure the ordering suffix matches the required tape and reel packaging specifications. Cross-reference the pinout diagram against the target PCB footprint to prevent installation errors due to package variations.

Selection Notes

Select this component when a dual NPN configuration with fixed biasing is required to reduce board space and assembly complexity. The 10k ohm internal resistor simplifies drive requirements compared to discrete transistors. Consider the 50V voltage rating and 100mA current limit to ensure adequate headroom for the intended application load conditions.

Part Context

This part belongs to the family of pre-biased bipolar junction transistors designed for surface-mount technology. It consolidates two transistors and one resistor into a single compact package, replacing multiple discrete components. The SMini6-F3-B form factor allows for automated placement in high-volume manufacturing environments.

Replacement Considerations

Check for direct substitutes within the same Panasonic series or equivalent dual NPN pre-biased transistors from other manufacturers that match the 50V rating, 100mA current capacity, and 10k ohm base resistance specification.
