LCP1521RL Datasheet PDF - ST Microelectronics

●DESCRIPTION

●This device has 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=5mAmax

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

●■ Holding current: IH= 150 mA min
