ESD2CAN24DCKRQ1 from TEXAS INSTRUMENTS, in a SC-70-3. 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 | bidirectional | ESD-protected bidirectional I/O that clamps to GND, rated for ISO 10605 ±27kV contact and air-gap discharge (330pF/330Ω), 5.7A IEC 61000-4-5 8/20µs surge, and ±24V reverse standoff voltage. |
| 2 | IO2 | bidirectional | ESD-protected bidirectional I/O that clamps to GND, rated for ISO 10605 ±27kV contact and air-gap discharge (330pF/330Ω), 5.7A IEC 61000-4-5 8/20µs surge, and ±24V reverse standoff voltage. |
| 3 | GND | power_in | Ground reference for the ESD clamp; the layout guidance calls for a thick, short return trace when pin 3 is grounded. |
