Philips Semiconductors Product specification
N-channel silicon field-effect transistors
FEATURES
• Low noise
• Interchangeability of drain and source connections
• High gain.
APPLICATIONS
• AM input stage in car radios
• VHF amplifiers
• Oscillators and mixers.
DESCRIPTION
N-channel symmetrical silicon junction field-effect
transistors in a SOT23 package.
CAUTION
The device is supplied in an antistatic package. The
gate-source input must be protected against static
discharge during transport or handling.
