Key Electrical Characteristics of the PHD45N03LT MOSFET

Followings are the key electrical characteristics of the PHD45N03LT MOSFET transistor

  • Maximum Drain-Source Voltage (VDS)

    • The maximum drain-source voltage that can safely block between drain and source in PHD45N03LT MOSFET transistor is 30V.

    This is the highest voltage the MOSFET transistor can safely block between the drain and source without damadging to the transistor.

  • Maximum Drain Current (ID)

    • The maximum continuous current flowing between the drain and source of the PHD45N03LT MOSFET transistor is 45A. This is the highest current that can safely flow between drain and source without damaging the MOSFET transistor.

  • Drain-Source On-State Resistance (RDS(on))

    • The internal resistance between the drain and source of PHD45N03LT MOSFET transistor when the transistor is fully turned on is 0.024 Ohm that defines the amount of lost power that is wasted as heat when the transistor is operating.

  • Maximum Power Dissipation (PD)

    • The maximum power that the PHD45N03LT MOSFET transistor can comfortably transfer into heat without breaking is 86W. This indicates the amount of power that can safely be dissipated to the device as heat.

  • Rise Time

    • The time that the drain current or output voltage increases between low to high when the PHD45N03LT MOSFET transistor is switched on is . This is the rate at which PHD45N03LT MOSFET transistor switches on.

    This shows how fast the MOSFET transistor switched on.

Thermal Performance of the PHD45N03LT MOSFET

  • Maximum Operating Junction Temperature

    • The maximum internal temperature of the semiconductor junction of PHD45N03LT MOSFET transistor can be safely operated at the 150°C without damaging the transistor.
