Vishay IRF740 Series Power MOSFET, 400V Maximum Drain Source Voltage, 125W Maximum Power Dissipation - IRF740PBF
This power MOSFET is a high-voltage N‑channel transistor designed for switching and amplification tasks in power electronics. It operates across a wide temperature range and is supplied in a through-hole TO-220AB package for conventional board mounting and heat‑sinking. The device supports high drain-source voltage environments and is suitable where robust switching capability and manageable gate‑drive requirements are needed.
Features and Benefits:
• 400V drain-source rating enables high‑voltage switching capability
• 10A continuous drain current supports substantial load currents
• 125W power dissipation allows sustained thermal handling
• 550 mΩ Rds(on) provides predictable conduction losses
• 63 nC typical gate charge reduces switching drive energy
• 20V maximum gate-source permits common gate‑drive voltages
• 10A continuous drain current supports substantial load currents

What thermal range can it tolerate in demanding environments?
The device is rated for operation from -55 °C up to 150 °C, enabling use in a wide range of thermal conditions.
How is the device mounted and cooled in typical designs?
It uses a TO-220AB through‑hole package that accommodates standard heatsinks and screws for thermal management and chassis attachment.
What gate‑drive limitations should designers observe?
The gate must be kept within ±20V maximum relative to source to avoid damage and to maintain correct enhancement‑mode operation.
What channel characteristics affect switching polarity?
It is an N‑channel enhancement‑mode device, meaning it requires a positive gate‑source voltage to conduct.
