1N5406 Diode Explained / Description

1N5406 is a high current diode available in DO-201 package. It has the maximum current 3A which is quite enough to drive a variety of loads and also a good feature to use in high current rectifier circuits.

It is a diode of 1N540X series which also contains other diodes such as 1N5400, 1N5401, 1N5402, 1N5403, 1N5404, 1N5405, 1N5407, 1N5408. All the diodes in this series have almost the same and can be used alternatively in some conditions. The important thing you should take into consideration when replacing with each other is their peak repetitive reverse voltage or (VRRM). You can replace a lower (VRRM) value diode only with the higher one but you cannot replace a higher (VRRM) diode with the lower one.

Looking at the technical specs of the diode the maximum peak repetitive reverse voltage is 600V, the maximum average rectified forward current is 3A, max non repetitive max forward voltage is upto 200A and max reverse current is 10uA.

The diode has many features such as peak surge overload 200A, low forward voltage drop, low leakage and high current capability of upto 3A due to which it can be used in variety of high current applications.


Where We Can Use It

1N5406 has variety of uses. First of all, it is a rectification diode so it can be used as a rectifier in many applications such as battery chargers, power supplies, inverters, etc. Additionally, it can also be used for protection purposes such as voltage blocking, spikes, and blocking voltage spikes.



Battery Chargers

Protection Purposes


Power Supplies

Low to high voltage rectification

AC to DC converters

Step up and step down converters

Blocking voltage and current in any desired direction


Safe Operating Guidelines / Absolute Maximum Ratings

To safely operate this diode it is important to check the absolute maximum ratings and the diode should be used below 20% of the absolute maximum ratings. The max reverse repetitive voltage is 600V therefore do not drive load of more than 480V. The maximum average rectified forward current is 3A therefore the derived load should be under 2.4A. The storage and operating temperature should be maintained between -65°C and 150°C.
