BOURNS Semiconductor TVS Diodes TVS Diode Arrays
Product Information
Specifications
- Maximum Impulse Voltage: 40 V
- Minimum Current Trigger Levels: 250 mA, 500 mA, or 750 mA
Product Usage Instructions
Overview
The TVS Diodes/TVS Diode Arrays offered by Bourns are designed to provide protection against transient voltage events in various electronic circuits.
Installation
- Identify the correct polarity of the TVS diode.
- Connect the TVS diode across the circuit that needs protection.
Operation
During normal operation, the TVS diode remains inactive, allowing the circuit to function without interference.
Overvoltage Protection
If an overvoltage event occurs, the TVS diode enters the active region, limiting the voltage across the circuit to ensure component protection.
