APPLICATION NOTES • Respect Thermal Resistance (PCB Layout) - as the temperature coefficient also contributes to the clamping voltage • 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 Document Number: 88366 Revision: 20-Oct-08 • Keep temperature of TVS lower than TOPSwitch® as a recommendation • Maximum current is determined by the maximum TJ and can be higher than 300 mA. Contact supplier for different clamping voltage/current arrangements • Minimum breakdown voltage can be customized for other applications.
