ESDA6V1SC5

STMicroelectronics · ESD And Surge Protection (TVS/ESD) · SOT-23-5L

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).
