What are the key features of 1N5820?
- 3A forward current capacity in a compact DO-201AD axial package, suitable for high-current rectification circuits
- Low maximum forward voltage of 0.85V minimizes conduction losses in power supply and freewheeling diode applications
- Isolated case connection in single-element silicon configuration enables straightforward circuit integration
What is 1N5820 used for?
The 1N5820 is commonly used as a freewheeling diode in switching power supplies and motor drive circuits to suppress inductive voltage spikes. It serves as a rectifier in low-voltage DC power conversion stages where a 20V blocking voltage and 3A current rating are sufficient. The DO-201AD through-hole package makes it easy to mount on standard PCBs in industrial and consumer power electronics designs.

Frequently Asked Questions
What is the maximum forward current the 1N5820 can handle continuously?
The 1N5820 is rated for a continuous forward current of 3A with a maximum forward voltage drop of 0.85V, making it suitable for moderate-power rectification and freewheeling applications in switching converters.
In which inductive load switching circuits is the 1N5820 typically used as a freewheeling diode?
The 1N5820 is used as a freewheeling diode across relay coils, DC motors, and solenoids operating up to 20V, where its 3A current rating and 0.85V forward voltage efficiently clamp inductive kickback and protect switching transistors.
How does the DO-201AD package of the 1N5820 affect PCB layout and heat dissipation?
The DO-201AD axial package allows horizontal through-hole mounting with lead spacing of approximately 15.24 mm, enabling good thermal contact with the PCB copper traces and supporting 3A continuous current without an additional heatsink in typical ambient conditions up to 25°C.
