ADVANCE INFORMATION for pre-production products; subject to change without notice.
The flyback diode reverse voltages for the positive and negative outputs are given respectively by Equation 33 and Equation 34.
Choose a 200-V, 1-A ultra-fast switching diode and a 100-V, 1-A Schottky diode for the positive and negative outputs, respectively, to allow some margin for inevitable voltage overshoot and ringing related to leakage inductance and diode capacitance. If needed, use a diode RC snubber circuit, for example 100 Ω and 22 pF, to mitigate such overshoot and ringing.
