1N4001-1N4007 are general purpose rectifiers produced by Fairchild Semiconductor Corporation. Their features are low forward voltage drop and high surge current capability.
The Fairchild 1N4001‑1N4007 series are general‑purpose rectifier diodes with low forward voltage drop and high surge current capability. The document lists absolute maximum ratings, features, and typical performance curves for the range.
Key electrical characteristics include forward voltage at 1 A, reverse current, peak repetitive reverse voltage, surge current, power dissipation, and thermal resistance. Thermal and storage temperature limits are also provided, along with characteristic curves for forward and reverse behavior.
| Forward Voltage (VF) @ 1 A | 1.1 V |
|---|---|
| Peak Repetitive Reverse Voltage (VRRM) | 50 V – 1000 V |
| Power Dissipation (PD) | 3.0 W |
| Thermal Resistance, Junction‑to‑Ambient (RθJA) | 50 °C/W |
| Operating Junction Temperature (TJ) | -55 °C to +175 °C |
| Storage Temperature Range (Tstg) | -55 °C to +175 °C |
At a forward current of 1 A, the 1N4001 has a forward voltage drop of about 1.1 V.
