BF908 - Dual-gate MOS-FETs

General Description

Depletion type field-effect transistor in a plastic microminiature SOT143 or SOT143R package.

The transistors are protected against excessive input voltage surges by integrated back-to-back diodes between gates and source.

The device is supplied in an antistatic package.

Key Features

  • High forward transfer admittance.
  • Short channel transistor with high forward transfer admittance to input capacitance ratio.
  • Low noise gain controlled amplifier up to 1 GHz.
