MPQ2484 TIN/LEAD

Overview

The MPQ2484 is a quad NPN low noise transistor array housed in a 14-pin TO-116 ceramic DIP package. It integrates four identical silicon die within a single metal-sealed cofired structure, providing a total power dissipation of 3.0 Watts at 25°C. The device features a collector-emitter breakdown voltage of 40V and a collector-base breakdown voltage of 60V. Key electrical characteristics include a minimum DC current gain (hFE) of 300 at IC=10mA and VCE=10V, an input capacitance (Cob) of 10pF, and a transition frequency (fT) of 50MHz.

Feature Summary

• Integrates four matched NPN transistors into a single monolithic unit for compact circuit design
• Utilizes a hermetically sealed ceramic metal-sealed cofired package for environmental protection
• Optimized for low noise amplification applications with high DC current gain

Applications

• Low noise amplifier stages in audio or RF circuits
• General purpose switching applications requiring multiple matched transistors
• Automotive exterior lighting driver circuits

Procurement Notes

Verify the specific ordering suffix required for plating options when placing orders. The TIN/LEAD suffix indicates tin-lead plating availability. Confirm current stock status as this component family may be subject to discontinuation notices from the manufacturer. Contact engineering support directly for technical data or alternate sourcing assistance if standard inventory is unavailable.

Selection Notes

Select this component when a quad NPN configuration is required in a through-hole DIP format. Ensure the 40V collector-emitter voltage rating meets the circuit requirements. Consider the 3.0W total power dissipation limit across all four dies when designing thermal management solutions. Verify that the low noise specifications align with the application's signal integrity needs compared to standard switching arrays.

Part Context

This part belongs to Central Semiconductor's MPQ series of quad transistor arrays. It serves as a direct replacement for the industry-standard 2N2484A quad NPN low noise transistor. The MPQ2484 provides a modern manufacturing alternative while maintaining the pinout and electrical characteristics of legacy discrete components, facilitating easier upgrades in existing designs.

Replacement Considerations

The manufacturer lists this part as End of Life with no official replacement part number available. Designers should consult the manufacturer's engineering team for potential alternate sources or substitute components that match the TO-116 footprint and electrical parameters.
