The onsemi ESD9B3.3ST5G is a compact bidirectional TVS diode designed to protect voltage-sensitive electronic components from electrostatic discharge (ESD) and transient voltage events. With a 3.3V working peak reverse voltage, 15 pF typical capacitance, low leakage current and a response time of less than 1 ns, it provides reliable protection while minimizing impact on circuit performance.
The device supports IEC 61000-4-2 ESD protection up to ±18 kV for both contact and air discharge. Its ultra-compact SOD-923 surface-mount package makes it especially suitable for space-constrained electronic designs, including smartphones, portable electronics, digital cameras, communication equipment and other sensitive electronic circuits.
