IRF2807 datasheet by International Rectifier

IRF2807 Frequently Asked Questions (FAQs)

• What is the maximum safe operating area (SOA) for the IRF2807?
  The maximum safe operating area (SOA) for the IRF2807 is not explicitly stated in the datasheet, but it can be estimated based on the device's thermal resistance and maximum junction temperature. A general rule of thumb is to limit the device to 50% of its maximum current rating for continuous operation.
• How do I ensure the IRF2807 is fully turned on?
  To ensure the IRF2807 is fully turned on, the gate-source voltage (Vgs) should be at least 10V for a logic-level MOSFET like the IRF2807. Additionally, the gate drive circuit should be able to provide sufficient current to charge the gate capacitance quickly.
• What is the maximum voltage rating for the IRF2807?
  The maximum voltage rating for the IRF2807 is 75V, but it's essential to consider the maximum drain-source voltage (Vds) and the maximum gate-source voltage (Vgs) separately. The maximum Vds is 75V, and the maximum Vgs is ±20V.
• How do I protect the IRF2807 from overvoltage and overcurrent?
  To protect the IRF2807 from overvoltage and overcurrent, consider using a voltage clamp or a transient voltage suppressor (TVS) to limit the voltage across the device. Additionally, use a current sense resistor and a fuse or a current limiter to prevent overcurrent conditions.
• What is the thermal resistance of the IRF2807?
  The thermal resistance (RθJA) of the IRF2807 is 62°C/W for the TO-220 package and 80°C/W for the TO-220FP package. This value represents the thermal resistance from the junction to the ambient air.
