MMPQ2222A

Overview

The MMPQ2222A is an NPN multi-chip general-purpose amplifier manufactured by onsemi. It integrates four discrete transistors within a single SOIC-16 surface-mount package. The device supports continuous collector currents up to 500 mA and features a collector-emitter breakdown voltage of 45 V, with a collector-base voltage rating of 75 V. Total power dissipation reaches 1,000 mW at 25°C ambient temperature. Electrical characteristics include a DC current gain (hFE) ranging from 35 to 300 depending on operating conditions, and a transition frequency (fT) of 300 MHz. The component operates reliably across a junction temperature range of -55°C to +150°C.

Feature Summary

• Integrates four independent NPN silicon transistors into a compact SOIC-16 package for space-efficient circuit design.
• Provides high medium-power amplification capabilities suitable for switching applications requiring up to 500 mA collector current.
• Offers robust thermal performance with a total device dissipation of 1,000 mW and effective junction-to-ambient resistance of 125°C/W.

Applications

• Medium power amplifier circuits
• General-purpose switching applications
• Multi-channel signal processing modules

Procurement Notes

Verify the specific ordering suffix against the official onsemi database before purchase. Ensure the documentation reflects the updated nomenclature following the Fairchild Semiconductor integration, as underscore characters in legacy part numbers have been replaced with dashes. Confirm that the SOIC-16 tape and reel packing method matches your automated assembly requirements.

Selection Notes

Select this component when multiple identical NPN switching stages are required in a limited footprint. Compare the 1,000 mW total dissipation against individual transistor alternatives to evaluate thermal management needs. Verify that the 45 V collector-emitter voltage rating meets the maximum supply requirements of the target application circuit.

Part Context

This device belongs to the FFB2222A/FMB2222A/MMPQ2222A family of NPN multi-chip general-purpose amplifiers. While the internal die specifications remain consistent across the series, the MMPQ2222A specifically utilizes the SOIC-16 package format. This distinguishes it from the SC70-6 and SSOT-6 variants offered under the same functional designation.

Replacement Considerations

Direct pin-compatible replacements within the same family include the FFB2222A and FMB2222A, provided the package type change is acceptable for the PCB layout. Cross-manufacturer equivalents should be evaluated based on matching hFE ranges, VCEO ratings, and SOIC-16 mechanical dimensions.
