1N4007 1A 1000V Rectifier Diode

Overview and Technical Specifications

The EIC 1N4007 is an industry-standard silicon rectifier diode engineered for high-efficiency power conversion, line-frequency rectification, and transient protection in AC-to-DC circuits. Encapsulated in a flame-retardant DO-41 plastic package with axial leads, this component offers a maximum repetitive peak reverse voltage rating of 1000 V (VRRM) and a continuous forward current rating of 1.0 A at an ambient operating temperature of 75 degrees Celsius.

Electrical Performance and Thermal Characteristics

Designed with a low forward voltage drop of maximum 1.0 V at rated current and a low reverse leakage current of just 5 microamperes at full rated VRRM, the 1N4007 minimizes internal power dissipation and thermal load. It boasts a high peak non-repetitive forward surge current capability of 30 A (8.3 ms single half sine-wave), providing crucial immunity against inrush currents during power supply turn-on sequences.

Application and Circuit Design Use-Cases

The 1N4007 standard recovery rectifier is ideal for full-wave and half-wave mains rectification in AC power adapters, offline switch-mode power supplies (SMPS), battery chargers, and consumer electronics appliances. Furthermore, due to its elevated peak inverse voltage rating, it serves as an excellent flyback or freewheeling diode across inductive loads such as relays, solenoids, and DC motors to absorb high-voltage inductive spikes and protect sensitive driver circuitry.
