With a high impedance at the stand-off voltage and low impedance at the breakdown voltage, silicon-avalanche diodes are well suited for ESD protection. As long as the capacitor has enough capacity that the energy from the pulse does not cause the voltage to raise above nominal level, the ESD is fully mitigated. Equipment Knobs. On the other hand, as shown in Fig. Thus, when the motor turns off, the diode presents a short circuit to the back EMF, allowing it to dissipate safely.
