Description :
Unidirectional double ElectroStatic Discharge (ESD) protection diodes in a common
cathode configuration, encapsulated in a SOT23 (TO-236AB) small Surface-Mounted
Device (SMD) plastic package. The devices are designed for ESD and transient
overvoltage protection of up to two signal lines.
Features
1. Unidirectional ESD protection of two lines
2. Bidirectional ESD protection of one line
3. Low diode capacitance: Cd≤140 pF
4. Rated peak pulse power: PPPM≤40 W
5. Ultra low leakage current: IRM≤5nA
6. ESD protection up to 30 kV (contact discharge)
Applications
1.Computers and peripherals
2. Audio and video equipment
3. Cellular handsets and accessories
4. Automotive electronic control units
5. Portable electronics
