1N4007 1A 1000V General Purpose Rectifier Diode Through Hole

1N4007 General Purpose Rectifier Diode – 1A 1000V Through Hole (DO-41)

The 1N4007 is the most widely used general-purpose silicon rectifier diode, rated for 1A forward current and a peak reverse voltage of 1000V. In the standard DO-41 axial package, it is a universal choice for AC-to-DC rectification, reverse polarity protection, and flyback suppression in power circuits.

Key Specifications

• Package: DO-41 (Through Hole, Axial)
• Peak Reverse Voltage (V₀₀₀): 1000V
• Average Forward Current (I₀): 1A
• Forward Voltage (V₀): ~1.1V at 1A
• Reverse Recovery Time: 30µs
• Power Dissipation: 3W
• Operating Temperature: −65°C to +175°C

Compatibility & Use Cases

The 1N4007 is used in power supply and protection circuits for Arduino, ESP32, NodeMCU, and other embedded systems. Common applications include:

• Bridge rectifier circuits for AC-to-DC conversion
• Reverse polarity protection on power input rails
• Flyback suppression diode across relay and motor coils
• Voltage clamping and snubber circuits
• DIY power supply and battery charger builds

Its 1000V rating makes it suitable for mains-connected circuits, while its 1A current capacity handles most low-power supply designs.
