Overview
The MPQ7043 PBFREE is a silicon NPN quad transistor array manufactured by Central Semiconductor Corp. It integrates four independent NPN transistors within a single TO-116 (14-pin DIP) package, designed for general-purpose amplifier and switching applications. Key electrical specifications include a collector-emitter voltage of 250V, continuous collector current of 500mA, and a transition frequency of 50MHz. The device supports an operating junction temperature range from -65°C to +150°C with a total power dissipation of 3.2W.
Feature Summary
- Integrates four independent NPN transistors in a single package
- High voltage capability suitable for demanding switching environments
- RoHS compliant construction without lead plating
Applications
- General purpose amplifier circuits
- Digital logic switching applications
- Interface circuitry requiring high voltage isolation
Procurement Notes
This component has been officially classified as End of Life by the manufacturer. Last time buy orders are non-cancellable and non-returnable. Procurement must adhere to specific timelines regarding final shipments and minimum order quantities established during the discontinuation notice period.
Selection Notes
Designers should verify that the required voltage and current ratings align with the 250V and 500mA limits. Due to the End of Life status, alternative sourcing strategies or redesigns using active components are recommended for new production runs to ensure long-term supply stability.
Part Context
The MPQ7043 belongs to Central Semiconductor's discontinued TO-116 case product line. This series includes other quad arrays such as the MPQ7053 and MPQ7093, which share similar form factors but differ in internal configurations. The entire group was transitioned to End of Life status due to declining customer demand.
Replacement Considerations
No direct replacement part numbers are available from Central Semiconductor for this model. Engineers must identify third-party equivalents or redesign the circuit to accommodate currently active discrete or array transistor solutions.
