MOSFET Characteristics Apparatus Trainer Kit

MOSFET Characteristics Apparatus Trainer Kit – Study N-Channel MOSFET Behaviour

Explore the electrical characteristics of a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) with this purpose-built MOSFET Characteristics Apparatus Trainer Kit. Designed for engineering and polytechnic students, this self-contained unit allows you to plot drain characteristics (ID vs VDS) and transfer characteristics (ID vs VGS) with precision and ease.

What’s in the Box

• Rugged blue metal enclosure with silk-screened front panel
• Two analog voltmeters — 5V DC (Gate circuit) and 25V DC (Drain circuit)
• One analog ammeter — dual range 5mA / 25mA for drain current measurement
• Dual independent DC power supplies:
  • VGS supply: 0–5V DC (adjustable via potentiometer)
  • VDS supply: 0–25V DC (adjustable via potentiometer)
• Built-in N-channel MOSFET (IRF Z44N) on the circuit board
• Series resistor RB in the gate circuit for protection
• Clearly printed circuit diagram on the panel for easy reference
• MAINS ON/OFF power switch with indicator
• Banana plug terminals (red/black) for all measurement points

Key Features

• Perform drain characteristics (Output characteristics: ID vs VDS at constant VGS)
• Perform transfer characteristics (ID vs VGS at constant VDS)
• Determine key MOSFET parameters: Transconductance (gm), Drain resistance (rd), and Amplification factor (μ)
• Dual-range ammeter for accurate low and high current readings
• Compact, durable design suitable for repeated lab use
• Ideal for ECE, EEE, and Physics lab practicals

Experiments You Can Perform

• Plot drain (output) characteristics of N-channel MOSFET
