# ESDSRVLC05-4

**Yint** · ESD Protection Devices · SOT-23-6L

ESDSRVLC05-4 from Yint, in a SOT-23-6L. 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 | I/O1 | passive | ESD-protected I/O line with rail-to-rail steering diodes, 0.9 pF typical to ground, 5 V reverse stand-off. |
| 2 | GND | power_in | Ground reference connected to the zener diode and the lower steering diodes; I/O pins are specified to this pin with 5 V stand-off. |
| 3 | I/O2 | passive | ESD-protected I/O line with rail-to-rail steering diodes, 0.9 pF typical to ground, 5 V reverse stand-off. |
| 4 | I/O3 | passive | ESD-protected I/O line with rail-to-rail steering diodes, 0.9 pF typical to ground, 5 V reverse stand-off. |
| 5 | VP | passive | Positive rail connection of the zener diode that the upper steering diodes return to; the datasheet does not name it. |
| 6 | I/O4 | passive | ESD-protected I/O line with rail-to-rail steering diodes, 0.9 pF typical to ground, 5 V reverse stand-off. |

## CAD (KiCad official)

- Symbol: `ESDSRVLC05-4`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6L (KiCad packages3D, STEP)
- 3D model files: `esdsrvlc05-4-etched.step` / `esdsrvlc05-4-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esdsrvlc05-4.step` / `esdsrvlc05-4.glb` are the bare package body.
