7.3 Feature Description

ESD321 provides ESD protection up to ±30-kV contact and ±30-kV air gap per IEC 61000-4-2 standard. During an ESD event, ESD diode connected to the I/O pin turns on and diverts the current to ground. Additionally, ESD321 also provides protection against IEC 61000-4-5 Surge currents up to 6 A (8/20 µs waveform) and up to 80 A per IEC 61000-4-4 (5/50 ns waveform, 4 kV with 50-Ω impedance) electrical fast transient (EFT) standard. The capacitance between the I/O pin and ground is 0.9 pF (typical) and 1.1 pF (maximum). The device features a low leakage current of 0.1 nA (typical) and 50 nA (maximum, across operating temperature range) with a bias of 3.6 V. The ESD diode at the I/O pin protects the ESD-sensitive devices by clamping the voltage to a low value of 6.8 V (IPP = 16 A 100 ns TLP ). The layout of this device makes it simple and easy to add protection to an existing layout. The package offers flow-through routing, requiring minimal modification to an existing layout.
