IRF3805STRLPBF datasheet by International Rectifier

IRF3805STRLPBF Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the IRF3805STRLPBF?
  The maximum operating temperature range for the IRF3805STRLPBF is -55°C to 175°C.
• Is the IRF3805STRLPBF a logic-level or standard MOSFET?
  The IRF3805STRLPBF is a standard MOSFET, which means it requires a higher gate-source voltage (typically 10V) to fully turn on.
• What is the maximum current rating for the IRF3805STRLPBF?
  The maximum current rating for the IRF3805STRLPBF is 38A, but this is dependent on the operating conditions and heat sink used.
• Is the IRF3805STRLPBF suitable for high-frequency switching applications?
  The IRF3805STRLPBF has a relatively high gate charge and output capacitance, making it more suitable for low-to-medium frequency switching applications (up to 100kHz). For high-frequency applications, a different MOSFET with lower gate charge and output capacitance may be more suitable.
• Can the IRF3805STRLPBF be used in a synchronous buck converter?
  Yes, the IRF3805STRLPBF can be used in a synchronous buck converter, but it's essential to ensure that the MOSFET is properly driven and that the converter is designed to minimize shoot-through currents and voltage ringing.
