Dual line programmable transient
voltage suppressor Wide negative firing
voltage range: VMGL = -150 V max. Low dynamic switching
voltages: VFP and VDGL Low gate triggering current: IGT = 5 mA max Peak pulse current: IPP = 15 A (10/1000 µs) Holding current: IH = 150 mA min
DESCRIPTION This device has been especially designed to protect 2 new high
voltage, as well as classical SLICs, against transient over
voltages. Positive over
voltages are clamped by 2 diodes. Negative surges are suppressed by 2 thyristors, their breakdown
voltage being referenced to -VBAT through the gate. This component presents a very low gate triggering current (IGT) in order to reduce the current consumption on printed circuit board during the firing phase. BENEFITS Trisils are not subject to ageing and provide a fail safe mode in short circuit for a better protection. Trisils are used to help equipment to meet various standards such as UL1950, IEC950 / CSA C22.2, UL1459 and FCC part68. Trisils have UL94 V0 resin approved (Trisils are UL497B approved (file: E136224)).
