FQI32N20CTU-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power DC-DC converter or motor drive module with system voltages up to 48V, 72V, or even above 100V, while also dealing with surge currents of 30A. Ordinary low-voltage MOS transistors break down under high voltage, while high-voltage MOS transistors often have high on-resistance and severe heating. VBsemi FQI32N20CTU-VB is designed for this—it integrates a 200V withstand voltage, 35A current capacity, and an on-resistance of only 50mΩ in a TO262 through-hole package, enabling high-voltage, high-current designs with both reliability and high efficiency.
