High-Current 1N5408 1000V 3A Silicon Rectifier Diode

Technical Specifications of 1N5408 5408 Rectifier Diode

• Maximum Peak Reverse Voltage: Capable of blocking up to 1000V in the reverse direction.

• Average Forward Current: Rated for a high continuous current of 3A at 75°C.

• Forward Voltage Drop: Features a maximum drop of 1.2V during high-current conduction.

• Peak Surge Current: Can withstand non-repetitive surge currents up to 200A for 8.3ms.

• Reverse Leakage Current: Maintains ultra-low leakage of 10uA at rated DC blocking voltage.

• Packaging: Encapsulated in a rugged DO-201AD plastic case for through-hole mounting.

• Construction: Reliable silicon junction design ensuring stable performance under heavy electrical loads.

• Compliance: This 1N5408 5408 Rectifier Diode is fully RoHS compliant and lead-free.

Circuit Implementation and Rectification Usage

• First, identify the cathode terminal by the silver band printed on the black body.

• Next, connect the anode to the AC source to begin the rectification process.

• Then, utilize four units in a bridge configuration for full-wave DC conversion.

• Afterward, install the diode in series to protect sensitive electronics from reverse polarity.

• Consequently, the 1N5408 5408 Rectifier Diode effectively suppresses high-voltage inductive spikes.

• Finally, ensure the cathode points toward the positive rail in standard power supplies.

Advantages and Disadvantages of 1N5408 5408 Rectifier Diode

• Pros: Offers a high 3A current rating in a compact, low-cost through-hole package.

• Furthermore, the 1000V rating provides a massive safety margin for mains-connected power circuits.

• Cons: The standard recovery time makes it unsuitable for high-frequency switching power supplies.

• Additionally, it generates heat during peak current operation requiring proper lead heat-sinking.

Precautions and Installation Safety

• Warning: Never exceed the 1000V peak reverse voltage to prevent catastrophic junction breakdown.

• Avoid operating the diode at 3A without adequate PCB trace thickness for heat dissipation.

• Do not apply reverse voltage higher than the rated limit during circuit testing.

What is Included in the Package

• 1x 1N5408 5408 Rectifier Diode (1000V 3A Silicon Rectifier).

• Pre-tinned axial leads for easy soldering and secure mechanical connection.
