可编程瞬态电压抑制器SLIC保护 PROGRAMMABLE TRANSIENT VOLTAGE SUPPRESSOR FOR SLIC PROTECTION

Description

These devices have been especially designed to protect 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.

Features

■ Dual programmable transient suppressor

■ Wide negative firing voltage range: VMGL= -150 V max.

■ Low dynamic switching voltages: VFPand VDGL

■ Low gate triggering current: IGT= 5 mA max

■ Peak pulse current: IPP= 30 A 10/1000 µs

■ Holding current: IH= 150 mA min

■ Low space consuming package
