MMPQ2222

Overview

The MMPQ2222 is a quad general-purpose NPN silicon transistor manufactured by Fairchild Semiconductor. It integrates four independent NPN transistors within a single surface-mount package, specifically the SOIC-16 configuration. The device supports a maximum DC collector current of 500 mA and withstands a collector-emitter voltage (VCEO) of 40 V. Additional electrical ratings include a collector-base voltage (VCBO) of 75 V and an emitter-base voltage (VEBO) of 5 V. The component operates with a maximum power dissipation of 1 W and features a minimum DC current gain (hFE) of 75. It offers a transition frequency (fT) up to 300 MHz, suitable for switching and amplification tasks across a temperature range from -55°C to 150°C.

Feature Summary

• Integrates four isolated NPN transistors in a compact multi-chip module
• Designed for high-speed switching and linear amplification applications
• Supports surface mount installation via standard SOIC footprint

Applications

• General purpose signal amplification circuits
• High-speed digital switching logic interfaces
• Multi-channel driver stages requiring compact form factor

Procurement Notes

Verify the specific manufacturer origin, as the MMPQ2222 designation was originally associated with Fairchild Semiconductor but is now produced under onsemi following corporate acquisition. Confirm that the datasheet references align with the intended design specifications. Ensure the package type matches the required PCB layout constraints. Check for any RoHS compliance documentation relevant to the production batch. Validate the pinout configuration against the target schematic to prevent integration errors during assembly.

Selection Notes

Select this component when space constraints necessitate multiple discrete transistors in a single package. Compare the 500 mA current rating against load requirements to ensure adequate headroom. Evaluate the thermal management capabilities given the 1 W power dissipation limit in the SOIC-16 package. Consider the 300 MHz transition frequency for high-speed application suitability. Verify compatibility with existing supply chains managed by onsemi or authorized distributors.
