1N4007-B
Product Overview
The 1N4007-B is a rectifier diode belonging to the category of semiconductor devices. It is commonly used in electronic circuits for converting alternating current (AC) to direct current (DC). The diode exhibits characteristics such as high current capability, low forward voltage drop, and fast switching speed. It is typically available in a DO-41 package and is widely used in power supply applications.
Specifications
- Maximum repetitive peak reverse voltage: 1000V
- Average forward current: 1A
- Peak forward surge current: 30A
- Operating temperature range: -65°C to +175°C
Detailed Pin Configuration
The 1N4007-B diode has two pins, an anode and a cathode. The anode is denoted by a longer lead or a positive sign on the body of the diode, while the cathode is marked with a shorter lead or a negative sign.
Functional Features
The 1N4007-B diode allows current to flow in only one direction, from the anode to the cathode, effectively acting as a one-way valve for electrical current. This property makes it suitable for use in rectification and power supply applications.
