MPQ2222 TIN/LEAD

Overview

The MPQ2222 is a quad NPN silicon transistor manufactured by Central Semiconductor Corp, housed in a 14-pin DIP package. It integrates four independent transistors within a single component for general-purpose amplifier and switching applications. Key electrical ratings include a collector-emitter voltage of 40 V, a continuous collector current of 0.5 A, and a power dissipation of 625 mW per transistor. The device operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Integrates four independent NPN silicon transistors into a single 14-pin dual in-line package
• Designed for general-purpose amplifier and switching circuit applications
• Provides high thermal stability with an extended operating junction temperature range

Applications

• General-purpose amplifier circuits
• Electronic switching applications
• Multi-channel signal processing systems

Procurement Notes

Verify the specific ordering suffix required for tin/lead plating when placing orders, as availability may vary by manufacturer batch. Confirm RoHS compliance status directly with the supplier, as leaded variants often fall outside standard environmental directives. Ensure the 14-pin DIP form factor matches the target PCB footprint before finalizing procurement decisions.

Selection Notes

Select this component when space efficiency requires multiple identical NPN transistors in a single package. The 40 V rating and 0.5 A current capacity suit low-to-medium power signal handling tasks. Verify that the through-hole mounting style aligns with the assembly process and that the quad configuration reduces bill-of-materials complexity compared to discrete single transistors.

Part Context

This part belongs to the Central Semiconductor quad transistor family, which consolidates multiple discrete devices into unified packages. The MPQ2222 specifically utilizes NPN silicon planar technology. It serves as a compact alternative to using four separate 2N2222-type transistors, simplifying layout and reducing component count in multi-stage designs.

Replacement Considerations

Direct pin-compatible substitutes include the MMPQ2222 or other quad NPN transistors in 14-pin DIP packages. Verify that replacement parts maintain equivalent voltage, current, and gain specifications to ensure circuit functionality remains unchanged during retrofitting.
