14D751K MOV Varistor

14D751K MOV varistor (750V), also known as VDR-14D751K, is developed for surge and overvoltage protection in AC power systems, industrial controls and electronic equipment. It offers fast response and dependable clamping behavior to help protect sensitive circuits from transient voltage spikes. Also known as: 14D751

This model is suitable for power input stages, industrial control panels and electrical assemblies where higher working voltage and consistent surge protection are required.

Key Electrical Characteristics:
Varistor Voltage (1mA): 750V ±10%
Maximum Continuous Voltage: 460VAC / 615VDC
Peak Surge Current (8/20μs): 4.5kA
Surge Energy (10/1000μs): 100J

The 14mm disc construction provides solid energy handling capability and stable performance for medium and high surge environments. The reference values above match the published data for TDK EPCOS S14K460 / B72214S0461K101.
