STB438A MOSFET Transistor Overview

The STB438A 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 TO263 package, making it suitable for projects that require moderate power handling and reliable switching performance.

Key Electrical Characteristics of the STB438A MOSFET

Followings are the key electrical characteristics of the STB438A MOSFET transistor

  • Maximum Drain-Source Voltage (VDS)

    • The maximum drain-source voltage that can safely block between drain and source in STB438A MOSFET transistor is 40V.

    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 STB438A 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 STB438A MOSFET transistor is 60A. 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 STB438A MOSFET transistor when the transistor is fully turned on is 0.0085 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 STB438A MOSFET transistor can comfortably transfer into heat without breaking is 62.5W. 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 STB438A MOSFET transistor is 248pF. This value influences to the switching speed of the STB438A 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 STB438A MOSFET transistor is switched on is . This is the rate at which STB438A MOSFET transistor switches on.

    This shows how fast the MOSFET transistor switched on.
