DMA261050R

Overview

The Panasonic DMA261050R is a dual silicon PNP epitaxial planar digital transistor designed for compact circuit integration. It features a Mini5-G3-B surface-mount package with dimensions of 2.9mm x 2.8mm x 1.1mm. The device provides a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. Total power dissipation is rated at 300 mW, with a junction temperature limit of +150 °C. Each internal transistor includes an integrated base input resistor (R1) with a typical value of 10 kΩ.

Feature Summary

• Dual configuration integrates two common emitter transistors into a single component to reduce board space and part count.
• Halogen-free packaging supports environmentally compliant manufacturing processes.
• Integrated base resistors simplify driver interface requirements and eliminate external biasing components.

Applications

• General-purpose switching in office equipment
• Signal processing within communications equipment
• Logic interfacing in measuring instruments
• Control circuits in household appliances

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm exact packaging quantities and reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure that the selected variant matches the required pinout and marking codes for your assembly process.

Selection Notes

Select this component when a dual PNP digital switch is required in a Mini5-G3-B footprint. Verify that the -50 V voltage rating and -100 mA current capacity meet the load requirements. Check that the 10 kΩ internal resistance aligns with the driving source capabilities. Consider thermal derating if ambient temperatures exceed standard operating ranges.

Part Context

This component belongs to the Panasonic DRA series of composite transistors. It serves as a direct replacement for the DRA2114T basic part number. The device is manufactured using silicon epitaxial planar technology optimized for high-density surface mount applications.

Replacement Considerations

The DRA2114T is the documented basic part number equivalent. Verify pin compatibility and electrical characteristics before substitution. No other specific substitute part numbers are confirmed in the provided datasheet.
