SLESDLC3V0L4 from Slkor SLKORMICRO Elec, in a SOT-553. 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 | IO | bidirectional | Connects to an I/O line for ESD and transient protection; the datasheet gives no pin-specific limits, only device-level ratings such as 5 V reverse stand-off voltage and 4.5 A peak pulse current (8/20us). |
| 2 | GND | power_in | Connects to ground, the common reference for the protection clamping of the I/O pins. |
| 3 | IO | bidirectional | Connects to an I/O line for ESD and transient protection; the datasheet gives no pin-specific limits, only device-level ratings such as 5 V reverse stand-off voltage and 4.5 A peak pulse current (8/20us). |
| 4 | IO | bidirectional | Connects to an I/O line for ESD and transient protection; the datasheet gives no pin-specific limits, only device-level ratings such as 5 V reverse stand-off voltage and 4.5 A peak pulse current (8/20us). |
| 5 | IO | bidirectional | Connects to an I/O line for ESD and transient protection; the datasheet gives no pin-specific limits, only device-level ratings such as 5 V reverse stand-off voltage and 4.5 A peak pulse current (8/20us). |
