This varistor is commonly used for overvoltage protection in various electronic circuits and devices.

Characteristics

  • Voltage Suppression: Capable of suppressing high voltage surges to protect sensitive electronic components.
  • Reliability: Provides reliable overvoltage protection for electronic circuits.
  • Fast Response Time: Reacts quickly to voltage surges to prevent damage to connected devices.

Package

The B72205S0301K311 varistor is typically available in a standard package suitable for surface mount applications.

Essence

The essence of this varistor lies in its ability to safeguard electronic circuits from voltage spikes and surges, thereby ensuring the longevity and reliability of electronic devices.

Packaging/Quantity

The varistor is usually packaged in reels or trays, with quantities varying based on the manufacturer's specifications.

Specifications

  • Model: B72205S0301K311
  • Voltage Rating: 30V
  • Nominal Discharge Current: 10kA
  • Maximum Allowable Voltage: 85V
  • Operating Temperature Range: -40°C to +85°C
  • Dimensions: 7.2mm x 5.4mm x 3.0mm

Detailed Pin Configuration

The B72205S0301K311 varistor features two terminals for connection to the circuit. The pin configuration is as follows: - Pin 1: Anode - Pin 2: Cathode

Functional Features

  • Voltage Clamping: When the voltage exceeds the varistor's threshold, it conducts current to limit the voltage across the circuit.
  • Transient Protection: Effectively absorbs and dissipates transient energy caused by voltage surges.
  • Non-linear Response: Exhibits a non-linear voltage-current characteristic, providing effective protection against sudden voltage spikes.

Advantages

  • Effective Protection: Safeguards electronic circuits from voltage transients and surges.
  • Compact Size: Small form factor makes it suitable for space-constrained applications.
  • Wide Operating Temperature Range: Can function effectively in diverse environmental conditions.

Disadvantages

  • Limited Lifespan: Varistors may degrade over time with repeated exposure to voltage surges.
  • Response Time: While fast, there may be a slight delay in response to extremely rapid voltage changes.

Working Principles

The varistor operates based on the principle of voltage-dependent resistance. Under normal operating conditions, it exhibits a high resistance. However, when the voltage exceeds a certain threshold, the varistor rapidly switches to a low-resistance state, diverting excess current away from the protected circuit.

Detailed Application Field Plans

The B72205S0301K311 varistor finds application in various fields, including: - Consumer Electronics: Protecting sensitive electronic components in TVs, computers, and home appliances. - Industrial Equipment: Safeguarding control systems, power supplies, and industrial machinery from voltage surges. - Automotive Electronics: Providing overvoltage protection in automotive control units and entertainment systems.
