P61089B - High Voltage Ringing SLIC Protector
This device has been especially designed to protect 2 new high voltage, as well as classical SLICs, against transient overvoltages.
Positive overvoltages are clamped by 2 diodes.
Negative surges are suppressed by 2 thyristors, their breakdown voltage being referenced to *VBAT through the gat
