Metal Oxide Varistor DISC 20mm ZOV-20D470K

From the shop's description

Metal Oxide Varistor DISC 20mm ZOV-20D470K The Zinc Oxide Varistor DISC 20mm ZOV-20D470K is a high-reliability voltage-dependent resistor designed for protecting low-voltage electronic circuits against transient overvoltage events such as switching surges, inductive spikes, and electrostatic discharge. Built using zinc oxide (ZnO) ceramic technology, this varistor provides highly nonlinear voltage-current characteristics, enabling rapid response and effective energy absorption. Features: Nominal varistor voltage of 47V with ±10% tolerance. High surge current capability up to 6.5kA (8/20µs). High energy absorption capability for transient suppression. Fast response time for effective overvoltage protection. Low leakage current and high insulation resistance. Radial leaded through-hole mounting. 20mm disc size for enhanced power handling. Wide operating temperature range from -40°C to +85°C. Specifications: Parameter Value Varistor Voltage 47V Voltage Tolerance ±10% Maximum AC Voltage 30VAC Maximum DC Voltage 38VDC Clamping Voltage 93V Peak Surge Current (8/20µs) 6.5kA Energy Absorption 70J~150J Capacitance ~5000pF@1kHz Mounting Type Through Hole Package Type Disc 20mm Lead Pitch 10mm Operating Temperature -40°C~+85°C Applications: Low-voltage DC power rail protection. Power supply input protection circuits. Industrial control systems. Consumer electronics and embedded devices. Automotive electronics protection. Communication and signal line protection.
