ESDA6V1-4BC6

STMicroelectronics · ESD And Surge Protection (TVS/ESD) · SOT-23-6L

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.
