Datasheet - BSZ110N08NS5ATMA1

Infineon OptiMOS 5 Series MOSFET, 80V Maximum Drain Source Voltage, 40A Maximum Continuous Drain Current - BSZ110N08NS5ATMA1

This MOSFET is a high-power N-channel semiconductor device designed for surface-mounted power switching and conversion in demanding environments. It operates across a wide temperature span suited to industrial tasks and delivers robust current handling with low voltage drop to support efficient power stages and compact thermal designs.

Features and Benefits:

• 80V drain voltage enables high-voltage switching applications
• 11mΩ low Rds(on) reduces conduction losses at high currents
• 40A continuous drain current supports heavy-load operation
• 15nC typical gate charge for fast, efficient gate switching
• 50W power dissipation allows significant heat handling
• 1.2V forward voltage minimises diode conduction losses

Applications

• Suitable for synchronous buck converters in power supplies
• Ideal for high-current motor-drive stages
• Used with DC-DC conversion modules in telecoms equipment
• Can be used for battery management and charging systems
• Appropriate for high-power LED driver circuitry

What mounting format is required for board assembly?

It is supplied in a PQFN package intended for surface-mount placement requiring a flat PCB land pattern and thermal vias for heat transfer.

How does the device handle thermal extremes during operation?

It is rated to operate from -55°C up to 150°C junction temperatures, permitting use in harsh industrial temperature profiles.

What gate-drive considerations are recommended?

The maximum gate-to-source rating is 20V and the typical total gate charge is 15nC, so a drive capable of rapid charge/discharge with appropriate slew control is advised.

Which conduction characteristic affects PCB thermal design?

Its low drain-source resistance of 11mΩ dictates lower I²R losses, shifting emphasis to managing switching and package thermal dissipation pathways.
