Vishay IRF820 Series Power MOSFET, 500V Drain-Source Voltage, 50W Power Dissipation - IRF820PBF
This power MOSFET is a high-voltage switching transistor designed for through-hole mounting in power conversion and control circuits. It operates as an N-channel enhancement device intended to switch or amplify high-voltage loads within electronic systems while meeting RoHS requirements.
Features and Benefits:
• 500V drain-source rating enables high-voltage switching capability
• 50W power dissipation supports sustained power handling
• 2.5A continuous drain current allows moderate load conduction
• 3Ω maximum RDS(on) reduces conduction losses under light loads
• 24nC typical gate charge permits reasonable switching speed control
• -55°C to 150°C operating range suits wide thermal environments

What package and mounting method does it use?
The device is supplied in a TO-220AB package configured for through-hole fitting with three pins for straightforward PCB attachment and heatsinking.
What gate voltage limits must be observed to avoid damage?
The gate-source voltage must not exceed 20V in either polarity to prevent gate-oxide stress and potential failure.
How does the forward voltage specification affect its use in circuits?
The specified forward voltage of 1.6V indicates the typical voltage drop when conducting under specified test conditions and should be accounted for in thermal and efficiency calculations.
Is this component suitable for automotive temperature extremes?
While it tolerates -55°C to 150°C, it is not designated to meet automotive-standard qualifications.
