LCDP1521 Datasheet (ST Microelectronics) - DUAL LINE PROGRAMMABLE TRANSIENT VOLTAGE SUPPRESSOR

LCDP1521, DUAL LINE PROGRAMMABLE TRANSIENT VOLTAGE SUPPRESSOR

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 gate.
