The 1N4007 is a widely used and readily available diode known as a rectifier diode. It is part of the 1N400x series of rectifier diodes, with each variant in the series having a specific reverse voltage rating. The 1N4007 is the highest voltage-rated diode in the series, with the following key features and specifications:
Voltage Rating: The 1N4007 is rated for a maximum reverse voltage (reverse breakdown voltage) of 1000 volts (1 kV). This makes it suitable for rectifying and blocking relatively high-voltage signals.
Current Rating: The 1N4007 is rated for a maximum average forward current (also known as the continuous forward current) of 1 ampere (1A). This current rating defines the maximum continuous current the diode can handle without overheating.
Package: The 1N4007 is typically available in a DO-41 package, which is a common axial-leaded package for diodes. It features two leads for easy mounting on a circuit board.
Reverse Recovery Time: The 1N4007 has a relatively slow reverse recovery time, typically in the range of microseconds. This means it is not suitable for high-frequency applications.
Forward Voltage Drop: The forward voltage drop of the 1N4007 is typically around 0.7 volts when conducting current in the forward direction. This voltage drop is relatively constant over a range of current levels.
Applications: The 1N4007 diode is primarily used for rectifying alternating current (AC) into direct current (DC) in power supplies, voltage clamping applications, and reverse voltage protection in circuits.
