The maximum voltage rating of the IRF520 is 100V, but it's recommended to operate it at a maximum voltage of 80V to ensure reliable operation and minimize the risk of breakdown.
To calculate the power dissipation of the IRF520, you need to know the drain-to-source voltage (Vds), drain current (Id), and the Rds(on) value. The power dissipation can be calculated using the formula: Pd = Vds x Id x Rds(on).
The maximum current rating of the IRF520 is 9.2A, but it's recommended to operate it at a maximum current of 5A to ensure reliable operation and minimize the risk of overheating.
To choose the correct heatsink for the IRF520, you need to consider the maximum power dissipation, operating temperature, and thermal resistance. A heatsink with a thermal resistance of 10°C/W or lower is recommended for the IRF520.
No, the IRF520 is a low-side switch and should not be used as a high-side switch. It's designed to switch the low-side of a load, and using it as a high-side switch can lead to incorrect operation and potential damage to the device.
