PESD1CAN TAN SOT-23 electrostatic discharge (ESD) protection diode

The PESD1CAN TAN SOT-23 electrostatic discharge (ESD) protection diode is a compact surface-mount protection component engineered to safeguard sensitive semiconductor circuits from transient electrostatic events. Packaged in a space-saving SOT-23 footprint, this device is intended for use where board area is limited and reliable surge protection is required.

Key attributes include a small form factor that facilitates high-density assembly and board-level protection for exposed interfaces. The diode offers fast transient suppression to help prevent damage to downstream components and supports placement close to connectors and I/O lines to improve overall system robustness.

Typical applications are protection of data and signal lines, ports and connectors, and general-purpose I/O in portable electronics, consumer devices, industrial modules, and communication equipment. The SOT-23 package enables automated pick-and-place assembly and is compatible with standard reflow soldering processes.

Designers will appreciate the straightforward integration of this protection diode into reference designs where electrostatic discharge mitigation is required without sacrificing PCB space. When paired with good board layout practices—such as short traces to the protected node and appropriate grounding—this device contributes to improved product reliability and field performance.

This product is sold under the designation shown and is intended for use by electronics designers, contract manufacturers, and repair technicians seeking a compact ESD protection solution in an industry-standard package.
