ESDS312DBVR

Texas Instruments · ESD And Surge Protection (TVS/ESD) · SOT-23-5

ESDS312DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected Not connected; reserved for optional straight-through routing and can be left floating or grounded.
2 GND power_in Ground connection; provides return path for surge and ESD currents.
3 NC unconnected Not connected; reserved for optional straight-through routing and can be left floating or grounded.
4 I/O1 bidirectional Surge/ESD protected channel with 4.5pF typical line capacitance; rated for ±30kV per IEC 61000-4-2 contact and air gap discharge protection.
5 I/O2 bidirectional Surge/ESD protected channel with 4.5pF typical line capacitance; rated for ±30kV per IEC 61000-4-2 contact and air gap discharge protection.
