Littelfuse has introduced the MMIX1T500N20X4, a 200V N-channel ultra-junction power MOSFET designed for high-current applications requiring low conduction losses and improved thermal performance.

Key Specifications:

  • Blocking Voltage: 200 V
  • Drain Current (ID): 480 A
  • On-Resistance (RDS(on)): 1.99 mΩ
  • Gate Charge (Qg): 535 nC
  • Thermal Resistance (Rth(j-c)): 0.14 °C/W
  • Isolation Voltage: 2500 VRMS

The device is housed in a ceramic-based, isolated SMPD-X package with topside cooling, which supports simplified thermal management and higher power density. Compared to other X4-Class MOSFETs, the MMIX1T500N20X4 offers significantly lower RDS(on) and higher current capability, allowing for consolidation of paralleled MOSFETs in system designs.

Target Applications:

  • DC load switching
  • Battery energy storage systems
  • Industrial power supplies and process control
  • Charging infrastructure
  • Power electronics for drones and VTOL platforms

This MOSFET is suitable for systems requiring compact, high-efficiency, and high-reliability solutions in medium-voltage ranges.
