DMA261020R

Overview

The Panasonic DMA261020R is a dual pre-biased PNP transistor array housed in the Mini5-G3-B (SC-74A/SOT-753) surface-mount package. It integrates two PNP transistors with built-in biasing resistors, each featuring a typical input resistance of 22 kOhms. The device supports a collector-emitter voltage of 50V and a continuous collector current of 100mA, with a total power dissipation rating of 300mW. Key electrical characteristics include a DC current gain (hFE) of 80, a collector cutoff current of 500nA, and a saturation voltage of 250mV at specified test conditions. It operates within a temperature range up to +150°C and holds an MSL rating of 1.

Feature Summary

• Integrates dual PNP transistors with internal biasing resistors for simplified circuit design
• Compact Mini5-G3-B surface-mount package suitable for space-constrained applications
• High thermal stability with a maximum operating temperature of +150°C

Applications

• General-purpose switching circuits requiring compact dual transistor solutions
• Interface logic level shifting between microcontrollers and peripheral devices
• Driver stages for low-power loads in consumer electronics

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required resistor tolerance and packaging format. Ensure storage conditions adhere to the moisture sensitivity level (MSL 1) guidelines to prevent solderability issues prior to assembly.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required to reduce board space and external component count. Compare against similar Mini5 packages if higher current ratings are needed. Verify that the 22kOhm input resistance aligns with the driving source impedance and desired switching speed requirements.

Part Context

This part belongs to Panasonic's digital transistor series, designed to replace discrete resistor-transistor networks. The Mini5-G3-B package offers a small footprint compared to traditional SOT-23 arrays, facilitating high-density PCB layouts in modern portable electronic devices.

Replacement Considerations

Potential substitutes include the DMA261030R (PNP, 47kOhm) or DMC261000R (NPN, 47kOhm), provided polarity and resistor values match the circuit design. Always verify pinout compatibility and electrical parameters before substitution.
