DMA261040R

Overview

The Panasonic DMA261040R is a dual PNP digital transistor housed in a Mini5 (SC74A/SOT753) surface-mount package. It integrates two pre-biased PNP transistors with internal base resistors, rated at 50V collector-emitter voltage and 100mA continuous collector current. Key electrical parameters include a DC current gain of 80, a saturation voltage of 250mV, and a power dissipation capacity of 300mW. The component features a collector cutoff current of 500nA and operates within standard commercial temperature ranges.

Feature Summary

• Integrates dual PNP transistors with built-in bias resistors to simplify circuit design
• Provides high-density packaging suitable for space-constrained applications
• Offers reliable switching performance with low saturation voltage

Applications

• General-purpose signal switching circuits
• Logic level translation interfaces
• Driver stages for small-signal loads

Procurement Notes

Verify the specific ordering suffix to ensure the correct resistance value and package variant are selected. Confirm active status with authorized distributors as supply chain conditions may vary. Request official datasheets to validate electrical characteristics against application requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual PNP switching functionality is required in a compact footprint. Ensure the 50V voltage rating and 100mA current limit exceed maximum circuit demands. Consider the integrated resistor values for proper base drive compatibility with upstream logic signals.

Part Context

This device belongs to Panasonic's digital transistor family, combining bipolar junction transistors with onboard resistors. The Mini5 package provides a compact solution compared to discrete component arrangements. It serves as a direct replacement for similar dual PNP digital transistors in existing designs requiring reduced board space.

Replacement Considerations

Cross-reference pinout configurations and internal resistor values when substituting with other manufacturers' dual PNP digital transistors. Verify that alternative packages maintain compatible thermal and electrical specifications for the intended application.
