- 40 V reverse breakdown voltage with 3 A continuous forward current rating in a compact DO-27 axial package
- Low forward voltage drop of 0.95 V max reduces conduction losses in power conversion circuits
- 80 A non-repetitive peak forward surge current capability for robust transient protection
Applications
The 1N5822 is widely used as a freewheeling diode across inductive loads such as relay coils, solenoids, and DC motors to suppress flyback voltage spikes. It is also deployed in low-voltage rectifier stages, polarity-protection circuits, and switching power supply output stages where its low forward voltage drop improves overall efficiency.

Frequently Asked Questions
What is the maximum continuous forward current the 1N5822 can handle, and what reverse voltage does it support?
The 1N5822 supports a maximum continuous forward current of 3 A and a reverse voltage rating of 40 V. Its forward voltage drop peaks at 0.95 V at rated current, which keeps conduction losses low in typical rectifier and freewheeling applications running from 12 V to 24 V supply rails.
How does the 1N5822 perform as a freewheeling diode on an inductive load such as a relay or solenoid driver?
Connected in reverse bias across an inductive load, the 1N5822 clamps the flyback spike to approximately 0.95 V above the supply rail during switch-off. Its 80 A non-repetitive peak surge rating absorbs the stored inductive energy without damage, making it a reliable freewheeling solution for 3 A drive circuits operating up to 40 V.
What physical package does the 1N5822 use, and how does it compare to smaller SMD Schottky alternatives?
The 1N5822 is housed in a through-hole DO-27 axial package, which is a 5.4 mm diameter cylindrical body with wire leads — substantially larger than SMD alternatives like the SMA (DO-214AC) or SMB packages. The axial form suits through-hole PCB designs or wire-wrapped prototypes where higher thermal mass is beneficial for handling 3 A continuous and 80 A surge currents.
