Key Features
- 600 V drain-to-source breakdown voltage with 9 A continuous drain current for robust high-voltage switching applications
- 255 mΩ typical RDS(on) enabling low conduction losses and high efficiency in resonant and hard-switching topologies
- PowerFLAT 5x6 HV package provides excellent thermal dissipation in a compact 5x6 mm SMT footprint
Applications
The STL18N60M6 is optimized for power factor correction (PFC) boost stages, LLC resonant half-bridge converters, and flyback SMPS designs operating from 85 V to 265 V AC mains. Its 600 V rating and low 255 mΩ RDS(on) make it a strong choice for server power supplies, industrial adapters, and EV on-board charger auxiliary rails. The PowerFLAT 5x6 HV package enables high-power-density designs with effective heat spreading on standard FR4 PCBs.

Frequently Asked Questions
What is the RDS(on) and current rating of the STL18N60M6, and how do they affect converter efficiency?
The STL18N60M6 has a typical RDS(on) of 255 mΩ and a continuous drain current rating of 9 A at 600 V. The low on-resistance reduces I²R conduction losses in PFC and resonant converter designs, directly improving full-load efficiency and lowering thermal stress on the MOSFET.
For which switched-mode power supply topologies is the STL18N60M6 best suited?
The STL18N60M6 is best suited for PFC boost converters, LLC series-resonant half-bridge converters, and flyback topologies operating from universal 85 V to 265 V AC inputs. Its 600 V drain voltage headroom and MDmesh M6 superjunction technology deliver low switching losses at frequencies above 100 kHz.
How does the PowerFLAT 5x6 HV package of the STL18N60M6 benefit board-level thermal management?
The PowerFLAT 5x6 HV package exposes a large exposed pad on the bottom, providing a low thermal resistance path to the PCB copper pour. This allows the STL18N60M6 to dissipate heat efficiently at 9 A continuous current without requiring a bulky heatsink, enabling slim adapter and charger designs with reduced PCB area compared to TO-220 or TO-263 packages.
