Download datasheetVHF power MOS transistor
Silicon N-channel enhancement mode vertical D-MOS transistor encapsulated in a 4-lead, SOT121B flange package with a ceramic cap. All leads are isolated from the flange. A marking code, showing gate-source voltage (VGS) information is provided for matched pair applications. Refer to the “General” section of the handbook for further information.
Features and benefits
- High power gain
- Low noise figure
- Easy power control
- Good thermal stability
- Withstands full load mismatch
Applications
- Large signal amplifier applications in the VHF frequency range
