1N4007 Rectifier Diode (1000V 1A)

Overview — 1N4007 Rectifier Diode (1000V 1A)

The 1N4007 Rectifier Diode is a widely used power diode in the 1N400x family, providing the highest voltage rating in the series. Designed for AC to DC rectification, surge protection, and general-purpose power management, the 1N4007 combines high reverse voltage with dependable forward current handling for hobbyist and industrial applications.

Key Features

• Reverse voltage up to 1000V for high-voltage circuits
• Continuous forward current of 1A for everyday rectification tasks
• Peak surge current (IFSM) up to 30A to handle inrush events
• Low forward voltage drop (~1.1V at 1A) for efficient operation
• Fast recovery characteristics and robust construction for long-term reliability
• Compact DO-41 axial package, easy to mount on PCB or breadboard

Installation and Usage Tips

• Observe correct polarity when placing the diode in series for rectification or protection.
• Provide adequate heat sinking or ventilation if operating near the 1A continuous limit to avoid thermal stress.
• For bridge rectifiers, use four 1N4007 diodes to convert AC mains to DC safely; ensure each diode meets the required voltage margin.
• Avoid repeated surge conditions above the IFSM rating to extend diode life.

Why Choose the 1N4007 for Your Design
