Overview
The MPSH81 is a PNP silicon RF transistor manufactured by Central Semiconductor Corp, housed in a TO-92 case. Designed for general-purpose RF amplifier applications, it features a collector-base voltage of 20 V and a continuous collector current rating of 50 mA. The device exhibits a transition frequency (fT) of 600 MHz at 100 MHz test conditions and maintains a power dissipation capacity of 350 mW. It operates within a junction temperature range of -65 to +150 °C, with an emitter-base voltage limit of 3.0 V.
Feature Summary
- Optimized for general-purpose radio frequency amplifier circuits
- High-speed switching capability indicated by 600 MHz transition frequency
- Robust thermal performance supporting operation up to 150 °C junction temperature
Applications
- General purpose RF amplification
- Radio frequency signal processing stages
- High-frequency switching applications
Procurement Notes
Verify the current production status before procurement as the MPSH81 has been classified as End of Life by the manufacturer. Confirm availability through authorized distributors or stock-only channels. Request updated datasheets to ensure compliance with specific design requirements. Validate lead times and minimum order quantities directly with suppliers due to potential supply constraints associated with discontinued components.
Selection Notes
Select this component for low-power RF amplifier designs requiring PNP topology. Ensure the operating environment stays within the specified -65 to +150 °C junction temperature range. Verify that the required collector current does not exceed 50 mA. Consider the TO-92 package constraints for thermal management and PCB layout. Evaluate alternative sources if long-term supply stability is critical for the product lifecycle.
Part Context
The MPSH81 belongs to the CP681 wafer process family from Central Semiconductor Corp. This specific process line has been discontinued and transitioned to End of Life status. The MPSH81 serves as a direct replacement part number within this legacy portfolio. Designers should be aware that production may be limited to existing stock or last-time buys.
Replacement Considerations
No official functional replacements are listed by the manufacturer. The MPSH81 is currently available only through stock-only channels. No cross-reference part numbers are provided in the official documentation.
