Key Electrical Characteristics of the AP9477GK-HF MOSFET

Followings are the key electrical characteristics of the AP9477GK-HF MOSFET transistor

Maximum Drain-Source Voltage (V_DS)

The maximum drain-source voltage that can safely block between drain and source in AP9477GK-HF MOSFET transistor is 60V.

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 (V_GS)

The maximum safe voltage that can be used between the gate and source of the AP9477GK-HF MOSFET transistor is 20V without any harm. This limit should not be exceeded to prevent damage from the gate voltage.

Maximum Drain Current (I_D)

The maximum continuous current flowing between the drain and source of the AP9477GK-HF MOSFET transistor is 4.1A. This is the highest current that can safely flow between drain and source without damaging the MOSFET transistor.

Drain-Source On-State Resistance (R_DS(on))

The internal resistance between the drain and source of AP9477GK-HF MOSFET transistor when the transistor is fully turned on is 0.09 Ohm that defines the amount of lost power that is wasted as heat when the transistor is operating.

Maximum Power Dissipation (P_D)

The maximum power that the AP9477GK-HF MOSFET transistor can comfortably transfer into heat without breaking is 2.8W. This indicates the amount of power that can safely be dissipated to the device as heat.

Drain-Source Capacitance

The capacitance between drain and source of the AP9477GK-HF MOSFET transistor is 55pF. This value influences to the switching speed of the AP9477GK-HF MOSFET transistor and the high-frequency performance.

This is the ability to hold a small electric charge between the drain and source of a MOSFET transistor, like a tiny built-in capacitor.

Rise Time

The time that the drain current or output voltage increases between low to high when the AP9477GK-HF MOSFET transistor is switched on is 6nS. This is the rate at which AP9477GK-HF MOSFET transistor switches on.

This shows how fast the MOSFET transistor switched on.

Thermal Performance of the AP9477GK-HF MOSFET

Maximum Operating Junction Temperature

The maximum internal temperature of the semiconductor junction of AP9477GK-HF MOSFET transistor can be safely operated at the 150°C without damaging the transistor.
