APPLICATION NOTES

• Respect Thermal Resistance (PCB Layout) - as the

temperature coefficient also contributes to the

clamping voltage

• Keep temperature of TVS lower than TOPSwitch

as a recommendation

• Maximum current is determined by the maximum

and can be higher than 300 mA. Contact

supplier for different clamping voltage/current

arrangements

• Minimum breakdown voltage can be customized for

other applications. Contact supplier

• Select minimum breakdown voltage, so you get

acceptable power dissipation and PCB tie point

temperature. Devices with higher breakdown

voltage will have a shorter conduction time and will

dissipate less power

• Clamping voltage is influenced by internal

resistance - design approximation is 7 V per

100 mA slope

• TOPSwitch is a registered trademark of Power

Integrations, Inc.
