1N483 Diode

Product Overview

The 1N483 diode is a semiconductor device belonging to the category of rectifier diodes. It is commonly used in electronic circuits for its ability to conduct current in only one direction, making it suitable for converting alternating current (AC) to direct current (DC). The diode's characteristics include low forward voltage drop, high reverse voltage capability, and fast switching speed. It is typically packaged in a small glass or plastic cylindrical enclosure and is available in various packaging quantities.

Specifications

  • Forward Voltage Drop: 0.7V
  • Reverse Voltage Capability: 200V
  • Maximum Forward Current: 1A
  • Package Type: DO-41
  • Packaging Quantity: 100 pieces per pack

Pin Configuration

The 1N483 diode has two leads, with the anode connected to the positive terminal and the cathode connected to the negative terminal.

Functional Features

The diode acts as a one-way valve for electric current, allowing current to flow in only one direction. It also provides protection against reverse voltage and minimizes voltage spikes in electronic circuits.

Advantages and Disadvantages

Advantages

  • Low forward voltage drop reduces power loss
