In one of our designs we are using ESD/EMI protection device IP4253CZ16-8-TTL. The datasheet for same does not provide any information about its clamping voltage. Typically other NXP datasheets show both clamped and unclamped waveforms from which we get an idea about what would be the clamping voltage. However no such waveforms are available in the datasheet of this device. does anyone / NXP has this information and can share with us?
