10 pcs : VESD09A4A-HSF-GS08 - ESD Suppressors / TVS Diodes 9.0 Volt 30 Watt 4-Line Quad

ESD Protection Diodes Vishay Semiconductor's ESD protection diode product line protects sensitive electronics from high transient voltages or unintentional frequencies. These Vishay Semiconductor protection diodes protect against the hazards of electrostatic discharges (ESD). Above the defined voltage working range, any transient voltage that approaches the breakdown voltage will be short-circuited by the diodes so it cannot reach the gate.
