Qorvo UJ3C120150K3S 1200V N-Channel Power MOSFET
The Qorvo UJ3C120150K3S is a high-voltage N-Channel power MOSFET designed for demanding power conversion and power supply applications. Utilizing advanced SiCFET (Cascode SiCJFET) technology, this device delivers high efficiency, low conduction losses, and excellent thermal stability, making it a reliable replacement component for the Bitmain Antminer APW11 power supply.
High-Voltage SiCFET MOSFET for Bitmain APW11 Power Supply Repair
With a 1200V drain-to-source voltage rating and a continuous drain current of 18.4A, the UJ3C120150K3S is engineered for high-power switching environments. Its low RDS(on) of 180mΩ and fast switching behavior help reduce power loss and improve overall PSU efficiency. The robust TO-247-3 package ensures effective heat dissipation and long-term operational reliability.

FAQ — UJ3C120150K3S SiC MOSFET
Q: Drop-in for silicon MOSFETs?
A: No — SiC MOSFETs have different gate-drive requirements (Vgs threshold, slew rate). Substitution requires matching gate-drive design or staying with same SiC family.
Q: Substitute SiC parts?
A: Other Qorvo / Wolfspeed / Infineon 1200V SiC MOSFETs in matching package + Rds(on) range. Verify gate-drive compatibility.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
