MMPQ3906

Overview

The onsemi MMPQ3906 is a quad PNP bipolar junction transistor array housed in a 16-SOIC surface-mount package. It integrates four independent PNP transistors within a single component, offering a maximum collector current of 200mA and a collector-emitter breakdown voltage of 40V. The device features a transition frequency of 200MHz and a maximum power dissipation of 1W. Key electrical specifications include a saturation voltage of 400mV at 5mA base and 50mA collector currents, with a minimum DC current gain (hFE) of 100 at 10mA collector current and 1V collector-emitter voltage.

Feature Summary

• Integrates four independent PNP transistors into a single compact surface-mount package for space-efficient circuit design.
• Provides high-speed switching capabilities supported by a 200MHz transition frequency suitable for general-purpose applications.
• Offers robust thermal performance with a 1W maximum power dissipation rating to handle moderate load requirements.

Applications

• General-purpose signal switching and logic interface circuits
• Driver stages for relays, solenoids, or indicator loads
• Complementary pairs in amplifier output stages

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact packaging configuration, such as tape-and-reel or cut-tape options. Ensure that the selected variant matches the required lead time and availability status for production timelines. Cross-reference the component marking code with official documentation to prevent counterfeit risks during sourcing.

Selection Notes

Select this component when a quad PNP configuration is required to minimize board space compared to discrete devices. Verify that the 40V voltage rating and 200mA current limit align with the target circuit's operational demands. Consider the 16-SOIC package dimensions for PCB layout constraints and ensure adequate thermal management for the 1W power dissipation capability.

Part Context

This component belongs to the standard small-signal BJT family, serving as a multi-channel alternative to single transistors like the MMBT3906. While the MMBT3906 offers similar electrical characteristics in a SOT-23 package, the MMPQ3906 provides four channels in a wider SOIC footprint, facilitating easier manual handling and higher power tolerance.

Replacement Considerations

Direct functional substitutes include other quad PNP arrays from various manufacturers, provided they match the 16-SOIC package and electrical ratings. Single-transistor equivalents like the MMBT3906 require four units per function. Verify pinout compatibility before substitution to avoid circuit damage.
