Infineon HEXFET Series MOSFET, 200V Maximum Drain Source Voltage, 18A Maximum Continuous Drain Current - IRFB4020PBF

This MOSFET is a power-switching transistor designed for high-voltage, high-current applications where robust thermal endurance is required. It operates as an N-channel enhancement device in a through-hole TO-220 package, providing a practical solution for discrete power stages and board-mounted switching circuits across a wide temperature range.

Features and Benefits:

• 200V drain rating enables high-voltage switching applications
• 18A continuous drain current supports substantial load currents
• 100W power dissipation permits elevated power handling
• 100 mΩ Rds(on) minimises conduction losses under load
• 18 nC typical gate charge yields faster switching transitions
• 1.3V forward voltage lowers diode conduction drop during recovery

Applications

• Suitable for motor-drive half-bridge stages
• Ideal for offline switch-mode power supplies
• Used with power converters requiring through-hole mounting
• Can be used for high-voltage relay and solenoid drivers
• Appropriate for laboratory prototypes and bench power experiments

What gate-voltage limits should designers observe for safe operation?

The gate-source voltage must not exceed ±20V to avoid damaging the gate oxide and to maintain reliable switching behaviour.

How does the device perform across temperature extremes?

It is rated to operate from -55 °C up to 175 °C, allowing use in environments with wide thermal variation while maintaining specified electrical characteristics.

What package considerations affect PCB layout and cooling?

The TO-220 through-hole form factor provides a single insulated mounting tab and allows direct attachment to a heatsink or chassis for improved thermal management.

How does the body diode influence switching-topology choice?

The intrinsic diode with a 1.3V forward drop should be accounted for in designs with reverse-recovery events to manage dissipation and determine snubber requirements.
