Pinout
The IRFP4768PBF features a standard TO-247 package, which generally includes three pins:
1. Gate (G): This pin is used to control the MOSFET's operation. A voltage applied here can turn the MOSFET on or off.
2. Drain (D): This pin is the main current-carrying terminal. It connects to the load and when the MOSFET is on, current flows from drain to source.
3. Source (S): This pin is connected to the ground or the negative side of the input supply. It completes the circuit for the current flow.
This MOSFET is commonly employed in power supply circuits, motor control applications, and other environments requiring high efficiency and fast switching.

Frequently Asked Questions
Q: Can the IRFP4768PBF be used in high-power switching applications at 250V?
A: Yes, its 93A continuous drain current and 17.5mOhm Rds(on) at 10V make it suitable for high-efficiency power supplies and converters.
Q: What is the maximum gate drive voltage allowed for this MOSFET?
A: The maximum gate-to-source voltage (Vgs) is ±20V. Infineon recommends a typical drive voltage of 10V for optimal Rds(on).
Q: How does the high input capacitance (10880 pF) affect switching speed?
A: High Ciss (10880 pF @ 50V) requires a stronger gate driver to achieve fast switching, but it benefits from low on-resistance for conduction losses.
Q: What is the intended package and mounting type for this part?
A: It comes in a TO-247AC through-hole package, ideal for high-power dissipation up to 520W with proper heatsinking.
Q: Is the IRFP4768PBF a current product or end-of-life?
A: Its status is “Last Time Buy,” so it is near discontinuation. Plan for last-time purchases or consider replacing with a newer Infineon HEXFET® series part.
Q: Can this MOSFET operate at very high temperatures?
A: Yes, it has an operating junction temperature range of -55°C to 175°C, suitable for rugged industrial environments.
