  • The ESDAxxxWx are monolithic suppressors designed to protect components connected to data and transmission lines against ESD.

    These devices clamp the voltage just above the logic level supply for positive transients, and to a diode drop below ground for negative transients.

    Key Features

    • 2 up to 5 Unidirectional Transil functions
    • Low leakage current < 1μA
    • Breakdown voltage: VBR = 6.1 V min. and 25 V min.
    • Very small PCB area < 4.2 mm2 typically
