Datasheet

Vishay IRF840A Series Power MOSFET, 500V Drain-Source Voltage, 8A Continuous Drain Current - IRF840APBF

This power MOSFET is a high-voltage N-channel transistor designed for switching and power conversion tasks in industrial and electronic systems. It operates across a wide temperature span and is packaged for through-hole mounting to support conventional PCB assembly and heatsinking approaches.

Features and Benefits:

• 500V drain-source rating enables high-voltage switching applications • 8A continuous drain current supports moderate load handling • 850mΩ Rds(on) reduces conduction losses in low-current designs • 125W power dissipation allows substantial thermal headroom • 38nC typical gate charge yields predictable switching behaviour • 30V gate-source limit ensures compatibility with common gate drivers

Applications

• Suitable for high-voltage power supply design and conversion tasks • Ideal for switching stages in automation control equipment • Used for motor drive front ends requiring through-hole components • Can be used for industrial inverter and converter prototypes • Used with discrete power boards requiring TO-220 mounting

What operating temperatures can I expect for reliable use?

The device is rated to operate from -55°C up to a maximum of 150°C, supporting harsh ambient conditions and elevated junction temperatures with appropriate thermal management.

What packaging considerations affect cooling and mounting?

The through-hole TO-220AB package with three pins permits direct attachment to heatsinks or chassis plates, facilitating conduction cooling and straightforward soldering onto traditional boards.

How does the gate charge influence driver selection?

With a typical gate charge of 38nC at specified gate drive, you should choose a gate driver capable of delivering sufficient Peak current to achieve the desired switching speed without excessive drive losses.

What voltage and current limits must designs respect?

Continuous drain current should be kept at or below 8A, and drain-source voltage must not exceed 500V to avoid device overstress.

Are there material or regulatory constraints to consider?

The component is supplied in a RoHS-compliant form, indicating adherence to standard restrictions on certain hazardous substances.
