Description
The 1N4001 is a general-purpose rectifier diode used in low-power rectification and protection circuits. It belongs to the 1N400x series, which consists of diodes with increasing voltage ratings.
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): 50V (maximum for 1N4001)
- Forward Voltage Drop (Vf): ~0.7V at 1A
- Reverse Recovery Time (trr): ~30µs (much slower than 1N4148)
- Power Dissipation (Pd): 3W
Applications:
- Low-voltage DC rectification (AC to DC conversion)
- Power supply circuits
- Reverse polarity protection
- Flyback diode in low-power inductive loads (e.g., small motors, relays)
Comparison with Other 1N400x Series Diodes:
| Diode | Reverse Voltage (Vr) |
|---|---|
| 1N4001 | 50V |
| 1N4002 | 100V |
| 1N4003 | 200V |
| 1N4004 | 400V |
| 1N4005 | 600V |
| 1N4006 | 800V |
| 1N4007 | 1000V |
The 1N4007 is the most commonly used in the series since it can handle up to 1000V, making it more versatile.
