2. Maximum Continuous Voltage:
• AC RMS Voltage: 460V
• DC Voltage: 615V
3. Energy Absorption Capability:
• Rated at 110 Joules for a single transient pulse (8/20 µs).
4. Peak Current (8/20 µs): 6,500 A (maximum).
5. Clamping Voltage: Approx. 1,240V at 25A.
6. Diameter: 14mm (disk type).
7. Response Time: Less than 25 nanoseconds.
8. Operating Temperature Range: -40C to +85C.

Uses

• Surge Protection: Protects electronic devices and circuits from high-energy transients caused by lightning strikes, power line surges, or switching events.
• Circuit Overvoltage Protection: Acts as a barrier for overvoltage events, preventing damage to components.
• Industrial Electronics: Used in motor control circuits, relays, and contactors.
• Consumer Electronics: Deployed in surge protectors, power strips, and power adapters.

Details

• Construction: The MOV-14D751K is composed of zinc oxide (ZnO) grains, enclosed in a non-conductive epoxy coating to ensure safety and durability.
• Non-Linear Response: Provides low impedance during overvoltage conditions and high impedance under normal conditions.
• Compact Design: 14mm diameter disc with radial leads for easy PCB mounting.
• High Energy Absorption: Effectively absorbs and dissipates transient energy without significant performance degradation.

Benefits

1. Enhanced Device Longevity: Protects sensitive electronic components from transient surges.
2. Quick Response: Extremely fast reaction time (<25ns) ensures reliable protection.
3. Cost-Effective Solution: Provides excellent surge protection at a low cost.
4. Wide Application Range: Suitable for industrial, residential, and commercial environments.
5. Robust Build: Designed to withstand environmental stress and mechanical vibrations.
