Functional Features

• Overvoltage Protection: When the voltage across the VDR exceeds its threshold, it rapidly decreases its resistance, diverting excess current away from the protected circuit.
• Transient Suppression: It effectively suppresses transient voltage spikes, safeguarding electronic devices from damage.

Advantages

• Effective protection against voltage surges
• Fast response time
• Wide operating temperature range

Disadvantages

• Limited lifespan after multiple surge events
• Susceptible to thermal runaway under extreme conditions

Working Principles

The VDRS05C275BSE operates based on the principle of voltage-dependent resistance. Under normal operating conditions, it exhibits high resistance. However, when subjected to overvoltage conditions, its resistance decreases sharply, providing a low-impedance path for excessive current.
