Infineon OptiMOS Series MOSFET, 100V Maximum Drain Source Voltage, 40A Maximum Continuous Drain Current - BSZ146N10LS5ATMA1

This MOSFET is a high-voltage, N-channel enhancement device intended for surface-mount power switching in electronic systems. It is built to operate across a very wide temperature span and is designed for applications requiring substantial current handling and thermal performance while being mounted in a compact PQFN package.

Features and Benefits:

• 100V drain tolerance enables high-voltage switching applications
• 40A continuous drain capability supports heavy current loads
• 14.6mΩ Rds(on) reduces conduction losses in power paths
• 52W maximum power dissipation improves thermal headroom
• 8nC typical gate charge allows faster switching transitions
• Vgs 20V rating permits robust gate-drive voltage margin

Applications

• Suitable for DC-DC converters in power supplies
• Ideal for synchronous rectification in power stages
• Used for motor-drive switching in industrial controllers
• Can be used for telecoms power distribution modules
• Used with compact, high-density surface-mount assemblies

What package type should I expect for compact board layouts?

It comes in a PQFN package designed for surface mounting to support high thermal transfer and low parasitic inductance.

How does the device behave in extreme ambient temperatures?

The permissible operating range spans from -55°C up to 150°C, enabling use in environments with wide temperature excursions.

What gate-charge considerations affect driver selection?

The typical gate charge is 8nC, so choose a driver with sufficient peak current to achieve the desired rise and fall times without excessive switching loss.

How should thermal management be approached for high-power use?

With a maximum dissipation of 52W, ensure adequate PCB copper, thermal vias and a heatsinking strategy to maintain junction temperatures within safe limits.
