DMA561020R

Overview

The Panasonic DMA561020R is a composite digital transistor featuring dual PNP transistors integrated into a single SMini5-F3-B package. It incorporates internal base resistors with a typical value of 20 kOhms, simplifying circuit design by reducing component count and board space. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Designed for surface mount technology, it operates at a maximum junction temperature of +150°C. This component is classified as an end-of-life product, indicating it is no longer in active production.

Feature Summary

• Dual PNP configuration within a compact footprint
• Integrated base resistors for simplified biasing
• High thermal stability suitable for demanding environments

Applications

• Switching applications in consumer electronics
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify availability through authorized distributors or secondary market suppliers, as the manufacturer has declared this part end-of-life. Confirm RoHS compliance status via the latest datasheet before integration. Evaluate long-term supply chain risks associated with discontinued components for new designs.

Selection Notes

Select this component only if existing designs require exact pinout and electrical characteristics matching the DMA561020R. Consider the dual PNP structure and 20 kOhm internal resistance when designing bias networks. Ensure the application does not require new production runs due to the discontinuation status.

Part Context

This part belongs to Panasonic's digital transistor family, specifically utilizing the SMini5-F3-B package. It serves as a replacement for discrete resistor-transistor networks, offering space savings in dense PCB layouts. The series typically includes variants with different resistor values and transistor polarities.

Replacement Considerations

Check for direct cross-references from other manufacturers offering identical dual PNP digital transistors in SMini5 packages. Verify that substitute parts match the -50V VCEO rating and -100mA current capacity. Ensure pin compatibility to avoid PCB redesign.
