Frequently Asked Questions
What are the voltage and current ratings of the STF11N65M5?
The STF11N65M5 is rated for a minimum drain-source breakdown voltage of 650V and a maximum continuous drain current of 9A. Its maximum RDS(on) is 0.48 Ω, making it suitable for high-voltage offline power conversion applications.
What is the avalanche energy rating of the STF11N65M5 and why does it matter?
The STF11N65M5 has a single-pulse avalanche energy (Eas) rating of 130 mJ. This high avalanche capability ensures the device can safely absorb voltage spikes caused by inductive loads, making it reliable in motor control and power supply designs without additional clamping circuitry.
What package does the STF11N65M5 use and is the tab electrically isolated?
The STF11N65M5 is housed in an isolated TO-220F (TO-220AB) package where the mounting tab is electrically isolated from the drain. This simplifies thermal management by allowing direct mounting to a heatsink without requiring additional isolation pads, reducing assembly cost and thermal resistance.
What MDmesh M5 technology features does the STF11N65M5 offer?
MDmesh M5 is STMicroelectronics' 5th-generation superjunction MOSFET technology, which achieves a significantly better RDS(on) x Qg figure of merit compared to earlier generations. This translates to lower conduction and switching losses, enabling higher efficiency in resonant, quasi-resonant, and hard-switching topologies.
What are common alternatives and typical applications for the STF11N65M5?
Typical applications include flyback SMPS, LLC converters, PFC boost stages, and industrial motor inverters. Compatible alternatives include the STF12N65M5 for slightly higher current, or Infineon's IPP60R099CS7 and ON Semiconductor's NTHL110N65S3 for comparable 650V N-channel MOSFET performance in similar packages.
