1N5408 Description

1N5408 is a 1N540x series diode. It is a general purpose diode with many good features, making it ideal for use in a wide range of general purpose applications. For example, it is capable of handling up to 3A or 3000mA of current across it.

 

It is manufactured in the DO201 package, which is a slightly larger DO-41 package, but can be used to replace many DO-41 diodes if a slightly larger space is available.

 

It's also an ideal diode if you're looking for a bit more ampere handling capability compared to DO-41 diodes, such as 1N4007, 1N4148, etc. In most applications, you can replace these diodes with 1N5408 in order to get more forward current.

1N5408 Replacement and Equivalent

1N5408 can easily be replaced by other diodes of its series, such as 1N5400, 1N5401, 1N5402, 1N5404, 1N5406 and 1N5407. The only differences between these diodes are the "Peak repetitive reverse voltage" and "Non repetitive reverse voltage’’, but as far as you use them in 12V to 24V circuits, there will be no problem.

 

But if you use them in circuits above 12V to 24V, then you must check their "Peak repetitive and non-repetitive reverse voltages" and select a higher "Peak repetitive reverse voltage" than your operating voltage. Other possible equivalents include P300M, CR3-100, CR3-120, G3M, FR307, FR607, HER508 and V3510.


Where to Use 1N5408 diode

As mentioned above, 1N5408 can be used in many applications, it is mainly build to perform rectification in battery chargers, power supplies, voltage boosters, etc. But other than that it can be used in any general purpose applications that can block current in the desired direction in a circuit, block voltage spikes, etc.


How to Safely Long Run in a Circuit

In order to achieve long-term performance in your project, circuit or device, it is suggested that you do not use this diode in circuits operating above 1000V, so that better performance is always kept below the maximum specification/characteristic values. Do not operate or drive more than 3A across this diode and always store and operate the device at temperatures above-65 centigrade and below +175 centigrade.


1N5408 Applications

  • Power Supplies

  • Battery Chargers

  • Voltage Doublers Circuits

  • Adapters

  • Rectification Circuits

  • Components Protection Purposes

  • Blocking voltage and current in any desired direction
