TVS/ESD Protection
OnChip offers a wide range of diode arrays that deliver outstanding protection against ESD and other voltage-induced transient pulses. These devices protect up to 8 transmission or data lines from spikes of up to 30 kV when tested per IEC-61000. For I/O ports with high data rates, OnChip offers ESD diodes with input capacitances as low as 0.5 pF. Due to their small size and ultra low leakage current these devices are best in class for space critical and power saving applications, including battery powered and handheld appliances.
