Overview
The MPSH17 is an NPN silicon epitaxial planar transistor designed for CATV applications. It operates with a collector-emitter voltage of 15 Vdc and a collector-base voltage of 20 Vdc. The device features a current-gain bandwidth product of 800 MHz at 5.0 mAdc and 10 Vdc. Electrical characteristics include a DC current gain range of 25 to 250, a saturation voltage of 0.5 Vdc maximum, and a noise figure up to 6.0 dB. Total device dissipation is rated at 350 mW at 25°C ambient temperature.
Feature Summary
- Designed specifically for broadband CATV amplifier and driver circuits
- Optimized for high-frequency small-signal performance with low noise characteristics
- Utilizes silicon epitaxial planar technology for reliable operation
Applications
- CATV amplifier stages
- Broadband driver circuits
- RF signal amplification in cable television systems
Procurement Notes
Verify the specific ordering suffix when purchasing. Suffixes such as RLRA or G indicate tape and reel packaging or lead-free composition respectively. Confirm package type matches TO-92 requirements. Ensure compliance with RoHS directives if lead-free variants are required for the assembly process. Check datasheet revision for updated thermal and electrical specifications.
Selection Notes
Select the MPSH17 for applications requiring high frequency response and low noise in CATV environments. Verify that the operating voltage remains within the 15 Vdc collector-emitter limit. Consider the thermal resistance of 357 °C/W for heat dissipation planning. Ensure the required DC current gain falls within the specified 25 to 250 range for the target bias conditions.
Part Context
The MPSH17 is manufactured by onsemi, formerly Fairchild Semiconductor. It belongs to the discrete semiconductor transistor category. The component is housed in a TO-92 (CASE 29-11) package. It serves as a specialized solution for cable television infrastructure, distinguishing it from general-purpose switching transistors through its optimized RF parameters.
Replacement Considerations
Consult official cross-reference lists for direct substitutes. Generic NPN transistors may not match the specific 800 MHz bandwidth or noise figure requirements. Verify pinout compatibility and thermal characteristics before substitution.
