Working Principles

The FS-387 is a bipolar junction transistor (BJT) that operates as an amplifier. It consists of three layers of semiconductor material: the emitter, base, and collector. When a small input signal is applied to the base-emitter junction, it controls the larger output current flowing through the collector-emitter junction. This amplification process allows weak signals to be boosted to a usable level.

Detailed Application Field Plans

The FS-387 transistor finds application in various electronic circuits, including:

  1. Audio Amplifiers: Enhances audio signals for improved sound quality.
  2. Radio Frequency (RF) Amplifiers: Boosts weak RF signals for better reception.
  3. Oscillators: Used in oscillator circuits to generate stable frequencies.
  4. Sensor Interfaces: Amplifies signals from sensors for accurate measurements.

Detailed and Complete Alternative Models

  1. FS-388: Similar characteristics, higher maximum collector current (800mA)
  2. FS-386: Similar characteristics, lower transition frequency (200MHz)
  3. FS-389: Similar characteristics, higher power dissipation (750mW)

These alternative models provide options with varying specifications to suit different application requirements.
