Product specification

Silicon N-channel dual gate MOS-FET

BF992

APPLICATIONS

• VHF applications such as VHF television tuners and FM

tuners with 12 V supply voltage. The device is also

suitable for use in professional communications

equipment.

DESCRIPTION

Depletion type field-effect transistor in a plastic

micro-miniature SOT143B package with source and

substrate interconnected.

The transistor is protected against excessive input voltage

surges by integrated back-to-back diodes between gates

and source.

PINNING

CAUTION

The device is supplied in an antistatic package.

The gate-source input must be protected against static

discharge during transport or handling.
