1N4049 Diode
Product Overview
The 1N4049 diode is a semiconductor device belonging to the category of rectifier diodes. It is commonly used in electronic circuits for its ability to allow current to flow in only one direction, making it ideal for converting alternating current (AC) to direct current (DC). The diode exhibits characteristics such as low forward voltage drop, high surge current capability, and fast switching speed. It is typically packaged in a glass-encapsulated DO-41 package and is available in various packaging quantities.
Specifications
- Forward Voltage Drop: 1V
- Reverse Voltage: 200V
- Maximum Forward Current: 1A
- Package Type: DO-41
- Packaging Quantity: 100 pieces per pack
Detailed Pin Configuration
The 1N4049 diode has two terminals: the anode and the cathode. In the DO-41 package, the anode is denoted by a band at one end of the diode, while the cathode is identified by the other end without a band.
Functional Features
The 1N4049 diode is designed to allow current to flow in only one direction, from the anode to the cathode, when a forward voltage is applied. This property makes it suitable for use in rectification and voltage regulation circuits.
Advantages and Disadvantages
