Infineon MOSFET Distributor | CoolMOS, OptiMOS Families
Genuine Infineon CoolMOS and OptiMOS power MOSFETs delivering low Rds(on) for efficient switching and battery management.
Infineon MOSFET Overview
BeiLuo supplies genuine Infineon power MOSFETs from the CoolMOS and OptiMOS families, offering industry-leading figure of merit for switching power supplies, battery management and motor control. CoolMOS 600 V super-junction devices such as the IPP60R099P6 deliver very low Rds(on) and reduced gate charge, improving efficiency in flyback, LLC and PFC stages. OptiMOS 150 V devices such as the IPP075N15N3G provide extremely low on-resistance with fast body-diode behavior for synchronous rectification and 48 V power distribution. Both families are available in TO-220, DPAK and D2PAK packages, simplifying thermal and mechanical design across power levels. As an authorized Infineon distributor, BeiLuo guarantees genuine, factory-traceable parts with import declaration documents, certificates of origin and RoHS compliance certificates on every shipment. Our engineering team assists with Rds(on) versus gate-charge trade-offs, thermal derating and package selection so your power stage meets efficiency and EMI targets. With buffer stock on mainstream 600 V and 150 V classes and consolidated shipping for mixed BOMs, we help OEMs and EMS partners keep production lines running without premium freight. Sample programs let your designers validate gate drive behavior and thermal performance before commitment, while volume pricing keeps unit cost predictable across multi-year production forecasts. Datasheet, import declaration and compliance documentation is provided with every shipment, so your supply chain stays audit-ready.

Frequently Asked Questions
How do I use the MOSFET table to compare parts?
Start with Vds to fix the voltage class, then compare Id and Rds(on) for current capability and conduction loss, and finally check Package and Temperature for your layout. Rds(on) is the strongest driver of efficiency in low-voltage, high-current stages.
Use the table to eliminate parts that fail voltage or thermal limits first.
How do I trade off Rds(on) against gate charge?
Lower Rds(on) reduces conduction loss but often comes with higher Qg, which raises drive loss and slows switching. In high-frequency converters gate charge matters more; in low-frequency, high-current paths Rds(on) dominates.
Compare the figure of merit (Rds(on) x Qg) for a quick ranking.
CoolMOS or OptiMOS: which family should I pick?
Pick CoolMOS 600 V super-junction parts for mains-connected PFC, flyback and LLC stages. Pick OptiMOS 150 V parts for low-voltage, high-current work such as synchronous rectification, 48 V distribution and battery protection.
Voltage class, not marketing name, should drive the first decision.
How do Vds and Id define my safe operating area?
Vds is the maximum drain-source voltage and Id is the continuous current at a stated case temperature. Real designs must also respect avalanche, SOA and thermal limits during transients.
Derate Id for your actual heatsink and ambient before selecting.
Which package is best for thermal performance?
TO-220 is simple and rugged but has higher mounting resistance; DPAK and D2PAK reduce thermal and electrical resistance for higher currents. Choose the package after you know your PCB copper budget and airflow.
Our FAE team can help match the package to your board capability.
How do the two MOSFET models in the table differ?
The IPP075N15N3G is a 150 V / 100 A OptiMOS device with 7.5 mΩ Rds(on) for 48 V rails and synchronous rectification. The IPP60R099P6 is a 600 V CoolMOS device with 99 mΩ for PFC, flyback and LLC stages.
They serve different voltage domains rather than competing directly.
How do I choose a MOSFET for a synchronous rectifier?
For synchronous rectification, prioritize low Rds(on) and good body-diode behavior, then confirm the gate charge suits your driver. OptiMOS 150 V parts are a common fit for 48 V and lower rails.
Watch dead-time and shoot-through when pairing high-side and low-side devices.
Are the MOSFETs in the table in stock?
Stock varies by model: some, like the IPP60R099P6, are held in regional warehouses while others are confirmed on request. Availability is shown on each model page.
