50/55 V for 36 V DC motors

Optimised SOA, high ID rating and excellent avalanche capability

There is growing demand for 36 V DC motors, often being used with multi-cell lithium-ion battery packs, in an increasing range of applications. From cordless power tools to outdoor power equipment and even e-bikes and scooters. To drive these demanding applications safely and efficiently requires MOSFETs that have been optimized for high current, strong SOA and rugged avalanche rating.

ASFETs for DC motor control – 50/55V ASFETs are designed to meet the needs of 36 V motors:

  • Nexperia’s Superjunction technology provides an enhanced Safe Operating Area (SOA) to withstand power dissipation due to short-circuit faults
  • ID(max) – LFPAK56E, enabling maximum torque from the motor and reliably managing high load and stall current conditions
  • Potential UIS (unclamped inductive spiking) energy dissipation 20% lower than a comparable 60 V MOSFETs
  • Nexperia’s low RDS(on) characteristics deliver higher efficiencies, ensuring longer battery life
  • As with all motor applications, there is a level of system vibration that cannot be dampened. LFPAK brings a unique level of board level reliability and ruggedness.
  • Devices are offered in logic level allowing them to be switched directly from a 5 V gate drive
