Description
The IRF740 is N-Channel, 400V, 10A, Power MOSFET.
The PowerMESH II is the evolution of the first generation of MESH OVERLAY. The layout refinements introduced greatly improve the Ron*area figure of merit while keeping the device at the leading edge for what concerns swithing speed, gate charge and ruggedness.
Pinouts:
Features
1. Exceptional dv/dt capability
2. 100% avalanche tested
3. Low gate charge
4. Very low intrinsic capacitances
Advantages
1. Its TO-220 package provides good thermal dissipation and makes it easy to mount on a heatsink.
2. It has a high voltage rating compared to the IRF640, making it suitable for high-voltage applications.
Disadvantages
1. The IRF740 has a relatively high gate capacitance, which may limit its use in high-frequency switching applications.
2. It is an N-channel MOSFET, which means it requires a positive gate voltage to turn on, making it incompatible with some circuits that require a negative gate voltage.
Applications
1. HIGH CURRENT SWITCHING
2. UNINTERRUPTIBLE POWER SUPPLY (UPS)
3. DC/DC COVERTERS FOR TELECOM, INDUSTRIAL, AND LIGHTING EQUIPMENT.
Absolute Maximum Ratings (Ta = 25°C)
