ESDA6V1-4BC6 from STMicroelectronics, in a SOT-23-6L. 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 | I/O1 | passive | ESD-protected signal/data/VCC bus line, bidirectionally clamped by two back-to-back Transil diodes to the common return node (pins 2/5); stand-off voltage VRM = 5V, breakdown voltage VBR = 6.1V min / 8V max, peak pulse power (8/20µs) = 80W. |
| 2 | GND | power_in | Common return/reference node for the internal ESD clamp diode pairs, directly wired to pin 5, forming the shared node between the back-to-back Transil diodes protecting the four I/O lines. |
| 3 | I/O3 | passive | ESD-protected signal/data/VCC bus line, bidirectionally clamped by two back-to-back Transil diodes to the common return node (pins 2/5); stand-off voltage VRM = 5V, breakdown voltage VBR = 6.1V min / 8V max, peak pulse power (8/20µs) = 80W. |
| 4 | I/O4 | passive | ESD-protected signal/data/VCC bus line, bidirectionally clamped by two back-to-back Transil diodes to the common return node (pins 2/5); stand-off voltage VRM = 5V, breakdown voltage VBR = 6.1V min / 8V max, peak pulse power (8/20µs) = 80W. |
| 5 | GND | power_in | Common return/reference node for the internal ESD clamp diode pairs, directly wired to pin 2, forming the shared node between the back-to-back Transil diodes protecting the four I/O lines. |
| 6 | I/O6 | passive | ESD-protected signal/data/VCC bus line, bidirectionally clamped by two back-to-back Transil diodes to the common return node (pins 2/5); stand-off voltage VRM = 5V, breakdown voltage VBR = 6.1V min / 8V max, peak pulse power (8/20µs) = 80W. Referenced in Figure 7 crosstalk test as I/O6. |
