Diode 1N4004 (5pcs)

The Diode 1N4004 is a general-purpose silicon rectifier diode rated for 1 A average forward current and 400 V peak reverse voltage, sold in a pack of 5. It belongs to the well-known 1N400x family and is used to convert AC to DC, protect circuits against reverse polarity and suppress voltage spikes from relay and motor coils.

Diode 1N4004 Specifications

• Type: silicon rectifier diode
• Peak repetitive reverse voltage: 400 V
• Average forward current: 1 A
• Surge current: 30 A (8.3 ms single half-sine)
• Forward voltage: up to 1.1 V at 1 A
• Package: DO-41, axial leads, through-hole
• Pack size: 5 pieces

Diode 1N4004 Applications

• Bridge and half-wave rectifiers in small power supplies
• Reverse polarity protection on DC inputs
• Flyback diodes across relays, solenoids and small DC motors
• Blocking diodes in battery and solar charging circuits
• Electronics education and repairs

What's in the Box

• 5 × 1N4004 rectifier diodes

Tip: The band on the body marks the cathode (−). For flyback protection, fit the diode across the coil with the cathode to the positive supply. It is a slow rectifier, so use a fast or Schottky diode in high-frequency switching circuits.
