The flyback diode reverse voltages for the positive and negative outputs are given respectively by Equation 33 and Equation 25.
Choose 100-V, 1-A and 60-V, 1-A Schottky diodes 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.
