MPQ2907 PBFREE

Overview

The Central Semiconductor MPQ2907 PBFREE is a quad PNP silicon transistor housed in a 14-pin TO-116 DIP package. It integrates four independent transistors designed for small signal, general purpose amplifier and switching applications. Key electrical ratings include a collector-base voltage of 60 V, a collector-emitter voltage of 40 V, and an emitter-base voltage of 5.0 V. The continuous collector current per transistor is rated at 600 mA, with a total package power dissipation of 2.0 W. Operating and storage junction temperatures range from -65 to +150 °C.

Feature Summary

• Integrates four independent PNP transistors within a single 14-pin TO-116 DIP package
• Designed specifically for small signal and general purpose amplifier applications
• Suitable for high-speed switching operations with defined transition frequencies

Applications

• Small signal amplification circuits
• General purpose switching applications
• Multi-channel logic interface designs

Procurement Notes

Verify the specific ordering suffix required for your application before purchasing. The manufacturer offers distinct plating options, including lead-free and tin/lead variants, which must be explicitly requested by adding the corresponding suffix to the part number during the order process. Confirm availability status as this component family may have specific discontinuation notices.

Selection Notes

Select this component when a compact solution for multiple PNP switching or amplification tasks is required. Ensure the design accommodates the 14-pin TO-116 footprint and verify that the 40 V collector-emitter voltage rating meets the circuit requirements. Consider the total package power dissipation limits when designing thermal management strategies for densely packed boards.

Part Context

This device belongs to the MPQ series of quad transistors manufactured by Central Semiconductor Corp. It shares functional similarities with other multi-transistor packages but is distinct in its specific pinout configuration and electrical characteristics tailored for PNP applications. The TO-116 case provides a standardized mechanical outline for through-hole mounting.

Replacement Considerations

Official documentation lists this part as End of Life (EOL) with no direct replacement provided by the manufacturer. Engineers should consult [email protected] for potential alternate sources or evaluate generic quad PNP transistors with compatible pinouts and electrical ratings.

FAQ

What is the maximum power dissipation for the entire MPQ2907 package?

The total package power dissipation is rated at 2.0 W, while each individual transistor has a power dissipation limit of 650 mW.

How are the pins configured in the TO-116 package?

The 14-pin DIP package assigns pins 1-3 to Collector, Base, and Emitter for Q1; pins 5-7 to Emitter, Base, and Collector for Q2; pins 8-10 to Collector, Base, and Emitter for Q3; and pins 12-14 to Emitter, Base, and Collector for Q4. Pins 4 and 11 are not connected.

Does the 'PBFREE' suffix indicate a change in electrical function?

No, the 'PBFREE' suffix only indicates that the device uses lead-free plating. It does not alter the electrical performance or functionality compared to standard versions.
