DMA261030R

Overview

The Panasonic DMA261030R is a dual pre-biased digital transistor featuring two PNP transistors integrated into a single Mini5-G3-B surface-mount package. It operates with a maximum collector-emitter voltage (VCEO) of -50 V and supports a continuous collector current of -100 mA. The device includes an internal typical input resistor of 47 kOhms, simplifying circuit design by eliminating external biasing components. It is rated for a maximum operating temperature of +150°C and offers a power dissipation capacity of 300 mW.

Feature Summary

• Integrates two PNP transistors with built-in bias resistors to reduce component count and board space.
• Features a compact Mini5-G3-B surface-mount footprint suitable for high-density PCB layouts.
• Designed for high-temperature reliability with a maximum junction temperature rating of +150°C.

Applications

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

Procurement Notes

Verify the current lifecycle status before integration, as this component may be subject to discontinuation. Confirm that the Mini5-G3-B package dimensions align with your PCB footprint library. Ensure thermal management strategies account for the 300 mW power dissipation limit under worst-case operating conditions. Validate RoHS compliance documentation if required for your specific market regulations.

Selection Notes

Select this component when a dual PNP configuration with fixed biasing is required in a minimal footprint. Compare against similar Mini5 packages from other manufacturers if supply constraints exist. Consider the -50 V voltage rating to ensure adequate headroom for your application's supply voltage. Evaluate the 47 kOhm input resistance value to confirm compatibility with your driving source impedance.

Part Context

This part belongs to Panasonic's series of composite digital transistors, which combine bipolar junction transistors with on-chip resistors. These devices are engineered to replace multiple discrete components, thereby improving circuit reliability and reducing assembly costs. The Mini5 package family provides various pin configurations for different transistor combinations.

Replacement Considerations

Check for direct cross-references within Panasonic's updated product lines. Verify functional equivalence of any substitute parts regarding pinout, voltage ratings, and current capabilities. Ensure alternative components maintain the same Mini5-G3-B or compatible package outline to avoid PCB redesign.
