Key Electrical Characteristics of the BUK9840-55 MOSFET

Followings are the key electrical characteristics of the BUK9840-55 MOSFET transistor

  • Maximum Drain-Source Voltage (VDS)

    • The maximum drain-source voltage that can safely block between drain and source in BUK9840-55 MOSFET transistor is 55V.

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

  • Maximum Gate-Source Voltage (VGS)

    • The maximum safe voltage that can be used between the gate and source of the BUK9840-55 MOSFET transistor is 10V without any harm. This limit should not be exceeded to prevent damage from the gate voltage.

  • Maximum Drain Current (ID)

    • The maximum continuous current flowing between the drain and source of the BUK9840-55 MOSFET transistor is 5A. 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 BUK9840-55 MOSFET transistor when the transistor is fully turned on is 0.04 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 BUK9840-55 MOSFET transistor can comfortably transfer into heat without breaking is 1.8W. 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 BUK9840-55 MOSFET transistor is switched on is . This is the rate at which BUK9840-55 MOSFET transistor switches on.

    This shows how fast the MOSFET transistor switched on.

Thermal Performance of the BUK9840-55 MOSFET

  • Maximum Operating Junction Temperature

    • The maximum internal temperature of the semiconductor junction of BUK9840-55 MOSFET transistor can be safely operated at the 150°C without damaging the transistor.
