ESD3V3WT is an ESD protection diode designed for suppressing electrostatic discharge on sensitive data lines and I/O ports in commercial-grade applications. The device features a snap-back characteristic with low junction capacitance and minimal leakage current, enabling effective transient suppression without degrading signal integrity. It offers exceptional ESD immunity with air discharge protection up to ±20 kV and contact discharge protection up to ±15 kV per IEC 61000-4-2 standards. The diode operates across a junction temperature range of -50°C to +125°C and is housed in a miniature SOD-523 package, making it ideal for space-constrained designs in consumer electronics, communication equipment, and industrial control systems requiring robust ESD protection.
