1. General description

Unidirectional double ElectroStatic Discharge (ESD) protection diode in a common cathode

configuration, encapsulated in a SOT23 (TO-236AB) small Surface-Mounted Device (SMD) plastic

package. The device is designed for ESD and transient overvoltage protection of up to two signal

lines.

2. Features and benefits

• Bidirectional ESD protection of one line

• Low diode capacitance: Cd ≤ 105 pF

• Rated peak pulse power: PPPM ≤ 40 W

• Ultra low leakage current: IRM ≤ 5 nA

• ESD protection up to 30 kV (contact discharge)

• IEC 61000-4-2; level 4 (ESD)

• IEC 61643-321

3. Applications

• Computers and peripherals

• Audio and video equipment

• Cellular handsets and accessories

• Portable electronics
