Part Number : BF998
Function : Silicon N-channel dual-gate MOSFET, Transistor
Package : SOT143B, SOT143R
Maker : NXP Semiconductors.
Depletion type field effect transistor in a plastic microminiature SOT143B or SOT143R package with source and substrate interconnected.
The transistors are protected against excessive input voltage surges by integrated back-to-back diodes between gates and source.
1. Short channel transistor with high forward transfer admittance to input capacitance ratio
2. Low noise gain controlled amplifier up to 1 GHz.
1. VHF and UHF applications with 12 V supply voltage, such as television tuners and professional
