ESDA5V3SC5 from STMicroelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IO1 | passive | ESD-protected I/O line 1; internally connected through a unidirectional Transil diode to the common node (pin 2), clamping positive transients near VBR and negative transients to about a diode drop below the common node. |
| 2 | COM | power_in | Common node joining the four internal unidirectional ESD clamp diodes shown in the functional diagram (Figure 1); serves as the reference/return node for pins 1, 3, 4 and 5. |
| 3 | IO2 | passive | ESD-protected I/O line 2; internally connected through a unidirectional Transil diode to the common node (pin 2), clamping positive transients near VBR and negative transients to about a diode drop below the common node. |
| 4 | IO3 | passive | ESD-protected I/O line 3, paired with pin 3 in the same diode bridge; internally connected through a unidirectional Transil diode to the common node (pin 2) for ESD clamping. |
| 5 | IO4 | passive | ESD-protected I/O line 4, paired with pin 1 in the same diode bridge; internally connected through a unidirectional Transil diode to the common node (pin 2) for ESD clamping. |
