ESDA6V1SC5 from STMicroelectronics, in a SOT-23-5L. 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 | IO1 | passive | ESD-protected I/O line 1; internally clamped by an anti-series diode pair referenced to the common pin 2, limiting positive transients to VCL and negative transients to a diode drop below the pin 2 reference (per functional diagram, Figure 1). |
| 2 | COM | power_in | Common node for all four internal ESD diode pairs, shown tied to the center junction of every channel in the ESDAxxSC5 functional diagram (Figure 1); serves as the ground/stand-off voltage (VRM) reference for clamping. |
| 3 | IO2 | passive | ESD-protected I/O line 2; internally clamped by an anti-series diode pair referenced to the common pin 2, limiting positive transients to VCL and negative transients to a diode drop below the pin 2 reference (per functional diagram, Figure 1). |
| 4 | IO3 | passive | ESD-protected I/O line 3, paired with pin 3 in the same diode network; clamped by an anti-series diode pair referenced to the common pin 2 (per functional diagram, Figure 1). |
| 5 | IO4 | passive | ESD-protected I/O line 4, paired with pin 1 in the same diode network; clamped by an anti-series diode pair referenced to the common pin 2 (per functional diagram, Figure 1). |
