The ESD5B5.0ST1G is a bidirectional Transient Voltage Suppressor (TVS)/Micro-packaged diode with UL94V-0 flame-rated void-free transfer-moulded thermosetting plastic case and 100% matte Sn (tin) finish. The ESD5B5.0ST1G is designed to protect voltage sensitive components from ESD. Excellent clamping capability, low leakage and fast response time provide best in class protection on designs that are exposed to ESD. Because of its small size and bidirectional design.
