LCDP1511D Datasheet - STMicroelectronics

DESCRIPTION
The LCDP1511D is a dual line protector which protects subscriber line interface circuits (SLIC) against transient overvoltages.
Positive overvoltages are clamped with diodes towards GND, while negative overvoltages are suppressed by thyristors connected to GND. The breakdown voltage of the thyristors is determined by the voltage applied to the gate, generally -Vbat.
   
FEATURES
■ Dual line programmable transient suppressor
■ Wide negative firing voltage range : VMGL = -80V
■ Low dynamic switching voltages : VFP and VDGL
■ Low gate triggering current : IGT = 5mA max
■ Peak pulse current : IPP = 15 A (10/1000 µs)
■ Holding current : IH > 150 mA
