Overview
The Central Semiconductor MPQ3904 PBFREE is a silicon NPN quad transistor housed in a 14-pin TO-116 DIP package. It integrates four independent transistors designed for general-purpose amplifier and switching applications. Key electrical ratings include a collector-emitter voltage of 40 V, a continuous collector current of 200 mA, and a total power dissipation of 2.0 W. The device operates within a junction temperature range of -65 to +150 °C.
Feature Summary
- Integrates four independent NPN transistors into a single component
- Designed for general-purpose amplification and switching tasks
- Utilizes a standard 14-pin dual in-line package
Applications
- General purpose amplifier circuits
- Digital logic switching applications
- Multi-channel signal processing designs
Procurement Notes
Verify the specific ordering suffix when sourcing this component. The datasheet indicates that adding the suffix PBFREE denotes lead-free plating, while TIN/LEAD specifies tin-lead plating options. Confirm the exact plating requirement matches your assembly specifications before placing orders with distributors or authorized suppliers.
Selection Notes
Select this component when a design requires multiple identical NPN switching elements in a compact through-hole format. The 14-pin configuration allows for efficient board space utilization compared to discrete components. Ensure the circuit voltage does not exceed the 40 V collector-emitter rating and that thermal management accommodates the total package power dissipation limits.
Part Context
This part belongs to the Central Semiconductor quad transistor family, offering a consolidated solution for multi-transistor requirements. It serves as an alternative to using four separate discrete NPN transistors, simplifying layout and reducing component count in general-purpose electronic designs.
Replacement Considerations
Direct pin-compatible replacements must match the 14-pin TO-116 footprint and provide equivalent NPN quad characteristics. Verify that substitute parts meet the 40 V collector-emitter voltage and 200 mA current requirements to ensure functional compatibility.
