VDRS05A020BSE

Product Overview

Category

The VDRS05A020BSE belongs to the category of Voltage Dependent Resistors (VDRs), also known as varistors.

Use

It is used to protect electronic circuits from overvoltage surges by providing a high resistance at normal operating voltage and a low resistance at overvoltage conditions.

Characteristics

• Voltage Rating: 20V
• Package: SMD (Surface Mount Device)
• Essence: Protection against voltage spikes
• Packaging/Quantity: Typically packaged in reels or tubes, with varying quantities depending on manufacturer

Specifications

• Maximum Allowable Voltage: 25V
• Clamping Voltage: 38V
• Peak Current Capability: 100A
• Operating Temperature Range: -40°C to 85°C

Detailed Pin Configuration

The VDRS05A020BSE typically has two terminals for surface mount soldering. The pin configuration may vary slightly based on the manufacturer's specifications.

Functional Features

• Overvoltage Protection: Provides a high resistance under normal conditions and rapidly switches to a low resistance state when an overvoltage surge occurs.
• Fast Response Time: Quickly responds to overvoltage events to protect sensitive electronic components.
• Reliability: Designed to withstand multiple surge events without degradation.

Advantages

• Effective protection against voltage surges
• Compact size for space-constrained applications
• RoHS compliant for environmental considerations

Disadvantages

• Limited lifespan after repeated surge events
• Requires proper circuit design for optimal performance

Working Principles

The VDRS05A020BSE operates based on the principle of Zener breakdown, where the material's resistance decreases sharply when the voltage exceeds the specified threshold.

Detailed Application Field Plans

• Consumer Electronics: Used in power supplies, telecommunication equipment, and home appliances.
• Industrial Equipment: Employed in motor drives, automation systems, and control panels.
• Automotive: Integrated into automotive electronics for surge protection.

Detailed and Complete Alternative Models

1. VDRS07A025BSE: Similar characteristics with a higher voltage rating of 25V.
2. VDRS03A015BSE: Lower voltage rating of 15V for applications with lower voltage requirements.
3. VDRS10A030BSE: Higher clamping voltage of 45V for increased surge protection.

In conclusion, the VDRS05A020BSE is a crucial component in safeguarding electronic circuits from damaging overvoltage events. Its compact size, fast response time, and reliability make it an essential part of various electronic applications.
