Additional Details

The ESD5Z5V is designed to meet IEC 61000-4-2 standards for ESD immunity. Its low clamping voltage is crucial for protecting sensitive components operating at low voltages. The device typically comes in a SOD-523 package. The clamping voltage is approximately 7V at an 8A surge current (tp=8/20μs). Its low capacitance (typically around 0.5pF) makes it ideal for protecting high-speed data lines such as USB 2.0. The operating junction temperature range is -55°C to +150°C. It's well-suited for applications where space is a premium, and robust ESD protection is essential.
