Description
The 1N4007 is a high-voltage rectifier diode commonly used in power supply circuits, AC-to-DC conversion, and reverse voltage protection.
Key Specifications:
- Type: General-purpose rectifier diode
- Material: Silicon
- Package: DO-41 (axial lead)
- Maximum Forward Current (If): 1A (continuous)
- Peak Surge Current (Ifsm): 30A (for 8.3ms)
- Reverse Voltage (Vr): 1000V (maximum)
- Forward Voltage Drop (Vf): ~0.7V at 1A
- Reverse Recovery Time (trr): ~30µs (not a fast-switching diode)
- Power Dissipation (Pd): 3W
Applications:
- AC to DC rectification (power supply circuits)
- Bridge rectifiers (for full-wave rectification)
- Reverse polarity protection (prevents damage from incorrect power connections)
- Freewheeling/Flyback diode in inductive circuits (relays, motors)
- HV (High Voltage) applications, since it can handle up to 1000V

Comparison: 1N4007 vs. 1N4148
| Feature | 1N4007 | 1N4148 |
|---|---|---|
| Type | Rectifier Diode | Fast-Switching Diode |
| Max Current (If) | 1A | 300mA |
| Reverse Voltage (Vr) | 1000V | 100V |
| Forward Voltage Drop (Vf) | ~0.7V | ~0.7V |
| Reverse Recovery Time (trr) | ~30µs (slow) | ~4ns (fast) |
| Applications | Power rectification | Signal switching |
If you’re designing a power supply or rectifier circuit, the 1N4007 is a great choice.
If you need fast switching, consider using a 1N4148 instead.
