IRF1405ZSPBF datasheet by International Rectifier

IRF1405ZSPBF Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the IRF1405ZSPBF?
  The maximum operating temperature range for the IRF1405ZSPBF is -55°C to 175°C.
• Is the IRF1405ZSPBF a logic-level or standard MOSFET?
  The IRF1405ZSPBF is a standard MOSFET, not a logic-level MOSFET. It requires a higher gate-source voltage to turn on fully.
• What is the maximum current rating for the IRF1405ZSPBF?
  The maximum current rating for the IRF1405ZSPBF is 194A, but this is dependent on the operating conditions and heat sink used.
• Is the IRF1405ZSPBF suitable for high-frequency switching applications?
  The IRF1405ZSPBF has a relatively high gate charge and output capacitance, making it less suitable for high-frequency switching applications above 100kHz.
• Can the IRF1405ZSPBF be used in a synchronous buck converter?
  Yes, the IRF1405ZSPBF can be used in a synchronous buck converter, but it may not be the best choice due to its relatively high Rds(on) and gate charge.
