Applications
The STF21N65M5 is well-suited for switched-mode power supplies, motor drive circuits, and industrial power conversion systems. Its high voltage rating and low on-resistance make it ideal for PFC (power factor correction) stages and LLC resonant converters. The isolated package configuration is particularly useful in designs requiring electrical isolation between the heat sink and circuit ground.
