CDLL5991 Encyclopedia Entry

Product Overview

CDLL5991 is a semiconductor device belonging to the category of diodes. It is commonly used as a rectifier diode in various electronic circuits. The diode exhibits characteristics such as low forward voltage drop, high current capability, and fast switching speed. It is typically packaged in a small, cylindrical glass package with two leads. The essence of the CDLL5991 lies in its ability to allow current to flow in only one direction, making it an essential component in rectifying AC to DC.

Specifications

  • Forward Voltage Drop: 0.7V
  • Maximum Reverse Voltage: 1000V
  • Maximum Forward Current: 1A
  • Package Type: Glass Cylinder
  • Quantity: Single unit

Detailed Pin Configuration

The CDLL5991 has two leads, with one lead connected to the anode and the other lead connected to the cathode. The anode lead is typically longer than the cathode lead for easy identification.

Functional Features

The CDLL5991 diode offers reliable rectification of alternating current to direct current, making it suitable for various power supply and signal processing applications. Its fast switching speed allows for efficient energy conversion.

Advantages and Disadvantages
