KP977AC MOSFET Transistor Overview

The KP977AC is a transistor, a MOSFET, used for on and off switching in electrical gadgets and power control applications. It is a N-Channel MOSFET, which means it conducts when a positive voltage is applied to the gate with respect to the source.

This device comes in a KT-81 package, making it suitable for projects that require high power handling and reliable switching performance.

Key Electrical Characteristics of the KP977AC MOSFET

Followings are the key electrical characteristics of the KP977AC MOSFET transistor

  • Maximum Drain-Source Voltage (VDS)

    • The maximum drain-source voltage that can safely block between drain and source in KP977AC MOSFET transistor is 65V.

    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 KP977AC MOSFET transistor is 20V 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 KP977AC MOSFET transistor is 30A. This is the highest current that can safely flow between drain and source without damaging the MOSFET transistor.

  • Maximum Power Dissipation (PD)

    • The maximum power that the KP977AC MOSFET transistor can comfortably transfer into heat without breaking is 320W. 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 KP977AC MOSFET transistor is 160pF. This value influences to the switching speed of the KP977AC 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 KP977AC MOSFET transistor is switched on is . This is the rate at which KP977AC MOSFET transistor switches on.

    This shows how fast the MOSFET transistor switched on.

Thermal Performance of the KP977AC MOSFET

  • Maximum Operating Junction Temperature

    • The maximum internal temperature of the semiconductor junction of KP977AC MOSFET transistor can be safely operated at the 150°C without damaging the transistor.
