The onsemi ESD9B5.0ST5G is a bidirectional Zener ESD protection diode rated at 5V max reverse standoff with a breakdown voltage minimum of 5.8V. It is designed for general-purpose ESD suppression on signal and data lines. The 15pF capacitance at 1MHz is low enough for high-speed interfaces such as USB 3.0 and HDMI, where excessive loading would degrade eye diagrams.
Housed in a SOD-923 surface-mount package, the footprint suits dense PCB layouts in mobile, wearable, and IoT modules.
The ESD9B5.0ST5G is an active onsemi part available through our distribution channel. Submit an RFQ with your target quantity and we will confirm current pricing and lead time. Tape & Reel and Cut Tape options are both orderable.
Yes — the 15pF capacitance is low enough to avoid signal degradation on 5 Gbps differential pairs, and the 5V reverse standoff covers the USB 3.0 VBUS and data-line voltage levels.
