CR Micro MOSFET Distributor | Super Junction and SGT
Genuine CR Micro Super Junction and SGT MOSFETs from 30 V to 650 V for supplies, PFC, LED drivers and motor-drive auxiliaries.
CR Micro MOSFET Overview
BeiLuo supplies genuine CR Micro silicon MOSFETs spanning planar, trench, SGT and Super Junction generations, with the Super Junction family covering 600 V and 650 V classes for offline power conversion and the SGT family lowering on-resistance in low-voltage synchronous rectification. CR Micro designs these devices on in-house 8-inch and 12-inch wafer lines, so supply, quality and long-term availability are controlled end to end rather than outsourced. The Super Junction parts use a charge-balanced drift region that trades the traditional RDS(on) versus breakdown-voltage compromise for markedly lower conduction loss at a given die area, which is why they are widely specified in switched-mode power supplies, power-factor-correction front ends, LED drivers and auxiliary supplies for motor drives and inverters. Devices such as the CRJQ80N65G4FQ and CRJSH38N65G4FQ bring 33 A and 72 A current ratings in TO-247 and T2PAK packages, covering the middle of the 650 V design space. The SGT series addresses 30 V to 150 V rails where switching loss and gate charge dominate, supporting synchronous rectification in adapters and telecom supplies. Every part we ship is factory-traceable and accompanied by import declaration, certificate of origin and RoHS documentation. Our FAE team helps you compare RDS(on), gate charge, output capacitance and thermal resistance, then confirm package, avalanche rating and EMC behaviour before you commit to a design.

Frequently Asked Questions
How do I use the MOSFET specification table to shortlist a part?
Start from the blocking voltage your bus requires in the VDS column, then narrow by continuous drain current in ID and by conduction loss in RDS(on). Package and Technology decide the mechanical and switching fit.
Filter by voltage and current first, then compare RDS(on) and gate charge at your switching frequency.
What is the difference between a Super Junction and an SGT MOSFET?
Super Junction devices use a charge-balanced drift region to combine high blocking voltage with low RDS(on), suiting 600-650 V offline supplies. SGT (shielded-gate trench) devices optimise low-voltage rails from 30 V to 150 V for synchronous rectification and battery paths.
Choose Super Junction for mains-referred stages and SGT for low-voltage secondary side switching.
How do RDS(on) and gate charge affect my losses?
Conduction loss scales with RDS(on) times the square of RMS current, while switching loss scales with gate charge and output capacitance times frequency. A part with low RDS(on) wins at high current and low frequency; low charge wins at high frequency.
Estimate both terms at your operating point before choosing.
Which package should I choose for my power level?
The TO-247 package supports medium to high current with a robust thermal path, the T2PAK and TOLL outlines reduce height and parasitic inductance for compact designs, and TO-220F offers an isolated tab for simple heatsinking.
Match the package to your board height, isolation and thermal budget.
