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 7V per 100mA slope. Keep temperature of TVS lower than TOPSwitch(R) as a recommendation. Maximum current is determined by the maximum TJ and can be higher than 300mA. Contact supplier for different clamping voltage / current arrangements. Minimum breakdown voltage can be customized for other applications. Contact supplier. |
