S20K275 Varistor 275V 20mm The S20K275 Varistor 275V 20mm Through Hole is a robust passive overvoltage protection component designed to safeguard electronic circuits and equipment against transient voltage spikes, surges, and electrical disturbances. Varistors are essential in AC mains protection, surge suppression modules, and power electronics to absorb dangerously high transient energies and prevent damage to sensitive components. Features: Metal oxide varistor (MOV) for overvoltage and surge protection. Designed for through‑hole mounting with radial solder leads for PCB applications. Nominal operating voltage 275 VAC for AC mains environments. High peak surge current handling capability up to 8000 A (8 kA, 8/20 µs). Specifications: Parameter Value Model S20K275 Technology Metal Oxide Varistor Varistor Voltage 430V ±10% Maximum AC Voltage 275Vrms Maximum DC Voltage 350V Clamping Voltage 710V Peak Surge Current (8/20μs) 8000A Energy Absorption (10/1000μs) 151J Typical Capacitance (at 1kHz) 850pF Operating Temperature –40°C to +85°C Disc Diameter 20mm Mounting Type Short Pin (Radial) Lead Pitch 10mm Applications: AC mains surge and transient voltage protection circuits. Power supply input protection and suppression. Consumer electronics surge safeguard. Industrial control and automation systems. EMI/RFI suppression in power lines. Package Include: 1x S20K275 Varistor 275V 20mm
