ESDA5V3SC6Y

ESDA5V3SC6Y is a six‑line ESD protection diode array (TVS) used to protect low‑voltage data lines from electrostatic discharges. The “5V3” indicates a nominal stand‑off voltage around 5.3 V, suitable for 5 V logic. “SC6” denotes six protection channels in a compact SC‑6 package; “Y” is a package/lot code. When an ESD pulse hits a channel, the corresponding diode clamps the transient to the supply rails, diverting current away from protected circuitry. Typical characteristics (per channel): very fast response (nanoseconds or less), low leakage, and low capacitance (often in the 0.3–1 pF range) to minimize impact on high‑speed signals. Applications include USB, CAN, I2C/SPI, LCD interfaces, and other 5 V or bidirectional data lines in consumer electronics. In short: a 6‑channel, low‑capacitance ESD suppressor for 5 V systems.
