DMA261060R

Overview

The Panasonic DMA261060R is a dual pre-biased PNP transistor array housed in an SC-74A (SOT-753) surface-mount package. It integrates two silicon PNP epitaxial planar transistors with internal base bias resistors, specified at 4.7 kΩ. Key electrical parameters include a collector-emitter breakdown voltage of 50V and a continuous collector current rating of 100mA. The device features a collector-emitter saturation voltage of -250mV and a DC current gain (hFE) of 80. Power dissipation is rated at 300mW, with a collector cutoff current of 500nA. It operates within standard temperature ranges and complies with RoHS standards.

Feature Summary

• Integrates dual PNP transistors with built-in base bias resistors to simplify circuit design
• Utilizes SC-74A surface-mount packaging for compact board space efficiency
• Provides high forward current transfer ratio with excellent linearity characteristics

Applications

• Digital logic circuits requiring integrated biasing
• Interface driver stages for microcontrollers
• Switching applications in consumer electronics

Procurement Notes

Verify component authenticity through authorized Panasonic distributors or certified agents. Confirm the specific ordering suffix matches the required resistor tolerance and tape-and-reel specifications. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines to prevent solderability issues during assembly. Cross-reference the manufacturer part number with official datasheets to validate revision levels before finalizing procurement orders.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required for digital switching. The 4.7kΩ internal resistor value suits standard logic interface voltages. Consider the 50V breakdown voltage and 100mA current limits against load requirements. The SC-74A package is suitable for high-density PCB layouts where space is constrained compared to larger discrete transistor arrangements.

Part Context

This component belongs to Panasonic's series of complex transistors designed for digital applications. It replaces multiple discrete components by combining transistors and bias resistors into a single miniaturized package. The product line focuses on reducing circuit complexity and improving reliability in portable and automotive electronic devices through integrated semiconductor solutions.

Replacement Considerations

Direct substitutes may include other dual PNP pre-biased transistors in SOT-753 packages with matching 50V ratings and similar bias resistor values. Verify pinout compatibility and thermal characteristics before substitution. Consult Panasonic technical documentation for approved alternative part numbers within the same product family.
