This device is a diode array designed to protect 1 line or 2 lines against ESD transients.
The device is ideal for applications where both reduced line capacitance and board space saving are required
It can also be used as bidirectional suppressor by connecting only pin 1 and 2.Key Features
- AEC-Q101 qualified
- Dual unidirectional Transil functions
- Low leakage current: IR max. < 20 µA at VBR
- 300 W peak pulse power (8/20 µs)
