Overview
The Central Semiconductor MPQ3798 PBFREE is a quad PNP silicon transistor housed in a 14-pin TO-116 DIP package. It contains four independent transistors designed for low-level and low-noise 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 device supports a continuous collector current of 50 mA per transistor with a total package power dissipation of 900 mW. Operating temperatures range from -65°C to +150°C.
Feature Summary
- Contains four independent PNP transistors within a single package
- Designed specifically for low-level and low-noise signal processing applications
- Utilizes a standard 14-pin dual in-line package (TO-116) for through-hole mounting
Applications
- Low noise amplifier circuits
- Precision analog switching arrays
- Low-level signal conditioning modules
Procurement Notes
Verify the specific ordering suffix required for your manufacturing process. The datasheet indicates that adding 'PBFREE' designates lead-free plating, while 'TIN/LEAD' specifies tin-lead plating. Confirm compliance with environmental regulations relevant to your assembly line before finalizing procurement orders.
Selection Notes
Select this component when multiple identical PNP transistors are required in a compact footprint. Ensure the circuit design accommodates the 40 V collector-emitter voltage limit and the 50 mA maximum collector current per channel. Verify that the thermal resistance characteristics fit the system's heat dissipation requirements.
Part Context
This part belongs to the MPQ series of quad transistors manufactured by Central Semiconductor Corp. It shares the same physical package and general topology as the MPQ3799, though they differ in specific voltage ratings. Both devices are classified as End of Life (EOL) products.
Replacement Considerations
Central Semiconductor lists no direct replacement part numbers for the MPQ3798. The manufacturer advises contacting [email protected] for assistance in locating alternate sources or suitable substitutes.
