SLESDLC3V0L4

Slkor SLKORMICRO Elec · ESD And Surge Protection (TVS/ESD) · SOT-553

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).
