Zinc oxide metal-oxide varistor is a 32D through-hole surge suppressor for overvoltage protection. It is rated for 550 VAC and 745 VDC maximum allowable voltage, with a 910 V varistor voltage at 1 mA and a 819 V to 1001 V tolerance range. The device supports 750 J maximum energy on a 10/1000 μs waveform and 25000 A withstanding surge current. Maximum clamping voltage is 1500 V at a 200 A test current, and typical capacitance is 1300 pF at 1 kHz.
