1N3477 Diode

Product Overview

The 1N3477 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 one direction, making it suitable for converting alternating current (AC) to direct current (DC). The diode exhibits characteristics such as low forward voltage drop and high reverse voltage capability. It is typically packaged in a glass-encapsulated DO-4 package, providing protection and efficient heat dissipation. The essence of the 1N3477 lies in its reliable and efficient rectification capabilities. Each package contains a single diode.

Specifications

  • Maximum Forward Voltage Drop: 1.1V
  • Maximum Reverse Voltage: 1000V
  • Maximum Average Rectified Current: 30A
  • Operating Temperature Range: -65°C to 175°C

Detailed Pin Configuration

The 1N3477 diode has a two-terminal configuration. The anode terminal is denoted by a longer lead, while the cathode terminal is identified by a shorter lead.

Functional Features

The 1N3477 diode functions as a unidirectional current conductor, allowing current flow only in the forward direction. Its low forward voltage drop ensures minimal power loss during conduction, making it suitable for high-efficiency applications.

Advantages and Disadvantages
