Vishay IRFI730G Series Power MOSFET, 400V Maximum Drain Source Voltage, 3.7A Maximum Continuous Drain Current - IRFI730GPBF

This power MOSFET is a high-voltage, N-channel switching transistor designed for through-hole mounting in power conversion and control circuits. It operates in enhancement mode and is suitable where compact TO-220 packaging and moderate current handling are required. The device is rated to operate across a wide ambient temperature span and complies with RoHS environmental restrictions.

Features and Benefits:

• 400V drain-to-source rating enables high-voltage switching
• 3.7A continuous drain current supports moderate load currents
• 1Ω maximum Rds(on) reduces conduction losses under load
• 35W power dissipation allows sustained thermal performance
• 38nC typical gate charge gives predictable switching behaviour
• 20V gate rating permits standard gate-drive voltages

Applications

• Used for switching in industrial power supplies
• Suitable for motor control in low-power drives
• Ideal for high-voltage LED driver stages
• Can be used for inverter front-end switching
• Used with discrete power control modules

What package and mounting style does it use?

It is supplied in a TO-220 package and intended for through-hole mounting, facilitating heatsinking on standard panels.

What thermal range can be expected during operation?

The component is specified to operate from -55°C up to 150°C, making it suitable for demanding thermal environments.

What gate-drive constraints should be observed?

The gate-to-source absolute rating is ±20V, so drive circuits should remain within this limit to avoid damage.

Is this device suitable for automotive qualification?

It is not specified as an automotive-standard part

selection should consider automotive qualification requirements separately.
