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
• Unidirectional ESD protection of two lines
• Bidirectional ESD protection of one line
• Very low diode capacitance: Cd ≤ 25 pF
• Reverse stand-off voltage: VRWM = 26 V
• Low clamping voltage: VCL = 49 V typ. at IPP = 2.8 A
• ESD protection up to 20 kV (IEC 61000-4-2)
• Ultra low leakage current: IRM = 1 nA typ.

3. Applications
• Computers and peripherals
• Audio and video equipment
• Cellular handsets and accessories
• Portable electronics
