IRF740 N-Channel MOSFET 400V/10A

The IRF740 is an N-channel power MOSFET that can switch loads up to 400V and 10A. MOSFET 740 has a low on-resistance of 55Ω, which makes it suitable for high-power applications.

The MOSFET 740 is commonly use in power switching and driver applications. IRF740 MOSFET can use to control motors, power supplies, and other high-power devices. The IRF740 is a reliable and versatile MOSFET that is suitable for a wide range of applications.

The IRF740 MOSFET has a drain to source voltage (VDS) rating of 400V. This means that it can withstand a maximum voltage of 400V between the drain and source terminals. The gate to source voltage (VGS) rating of the IRF740 is +/- 20V. This means that the gate voltage can be anywhere from -20V to 20V without damaging the MOSFET. The gate to threshold voltage (VGS (th)) of the IRF740 is 2V to 4V. This means that the gate voltage must be at least 2V to turn the MOSFET on.

In addition to the voltage ratings, the IRF740 also has a maximum power dissipation rating of 125W. This means that the MOSFET can dissipate a maximum of 125W of heat without overheating. The IRF740 also has a maximum drain current rating of 10A. This means that the MOSFET can safely carry a maximum current of 10A.

It is important to note that the voltage and current ratings of the IRF740 are only the maximum ratings. It is always best to operate the MOSFET within its safe operating area (SOA) to prevent damage. The SOA is a graph that shows the maximum voltage, current, and temperature that the MOSFET can withstand for a given amount of time.

The IRF740 MOSFET is a versatile and powerful device that can use in a wide variety of applications. 

Features : –

The IRF740 MOSFET is a type of field-effect transistor (FET) that works by controlling the flow of current between the drain and source terminals using a voltage applied to the gate terminal. The 740 is an N-channel MOSFET, which means that the current flows from the drain to the source when the gate voltage is positive. The 740 MOSFET is a versatile and powerful device that offers a number of benefits, including:

• High voltage and current ratings
• Low on-resistance
• Fast switching speed
• High efficiency
• Rugged construction
• Wide availability
