What are the key features of STFU11N65M2?
- 650 V drain-source breakdown voltage supporting direct switching from 400 V rectified mains in power supplies and inverters
- 0.60 Ω typical on-resistance at 7 A enabling low conduction loss in mid-power AC-DC converter stages
- MDmesh M2 technology optimizing the figure of merit (Rds_on × Qg) for high-frequency switching efficiency
What is STFU11N65M2 used for?
The STFU11N65M2 is designed for offline AC-DC power conversion applications including flyback converters, LLC resonant converters, and PFC boost stages operating from 230 V or 110 V mains. Its 650 V rating and 0.60 Ω on-resistance make it suitable for adapter power supplies up to 50 W, lighting ballasts, and industrial SMPS where TO-220FP through-hole mounting simplifies heatsink attachment. The MDmesh M2 superjunction technology provides a low gate charge for efficient operation at switching frequencies up to 200 kHz.

Frequently Asked Questions
What continuous drain current does STFU11N65M2 support and at what on-resistance?
The STFU11N65M2 is rated for 7 A continuous drain current with a typical on-resistance of 0.60 Ω and a maximum of slightly higher at elevated temperatures. At 7 A conduction, resistive power dissipation is approximately 29 W, so adequate heatsinking through the TO-220FP package is required for designs operating near full current rating in ambient temperatures above 25°C.
For which offline power converter topologies is STFU11N65M2 best suited given its 650 V rating?
The 650 V breakdown voltage of STFU11N65M2 provides sufficient margin above the 400 V DC bus present in 230 V AC mains rectifier circuits, accounting for line transients and ringing peaks. It is best suited for single-switch flyback converters up to 50 W, active clamp flyback designs, and boost PFC stages where the switch node voltage swings to 400 V plus 50% overshoot, making the 650 V rating the industry-standard choice for this class of converter.
How does MDmesh M2 technology in STFU11N65M2 improve switching performance compared to standard planar MOSFETs?
MDmesh M2 uses a superjunction column structure to reduce on-resistance per unit area by 5× to 10× compared to standard planar high-voltage MOSFETs, while also lowering gate charge (Qg) to achieve a better Rds_on × Qg figure of merit. In a 100 kHz flyback converter, the reduced gate charge translates to lower gate drive power loss and faster switching transitions below 50 ns, improving overall converter efficiency by 0.5% to 1.5% compared to a conventional 650 V planar MOSFET at the same on-resistance.
