2SJ125 MOSFET Transistor Overview

The 2SJ125 is a transistor, a MOSFET, used for on and off switching in electrical gadgets and power control applications. It is a P-Channel MOSFET, which means it conducts when a negative voltage is applied to the gate with respect to the source.

This device comes in a SOT23 package, making it suitable for projects that require low power handling and reliable switching performance.

Key Electrical Characteristics of the 2SJ125 MOSFET

Followings are the key electrical characteristics of the 2SJ125 MOSFET transistor

  • Maximum Drain-Source Voltage (VDS)

    • The maximum drain-source voltage that can safely block between drain and source in 2SJ125 MOSFET transistor is 50V.

    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 2SJ125 MOSFET transistor is 0.01A. 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 2SJ125 MOSFET transistor when the transistor is fully turned on is 220 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 2SJ125 MOSFET transistor can comfortably transfer into heat without breaking is 0.15W. 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 2SJ125 MOSFET transistor is switched on is . This is the rate at which 2SJ125 MOSFET transistor switches on.

    This shows how fast the MOSFET transistor switched on.

Thermal Performance of the 2SJ125 MOSFET

  • Maximum Operating Junction Temperature

    • The maximum internal temperature of the semiconductor junction of 2SJ125 MOSFET transistor can be safely operated at the 125°C without damaging the transistor.
