# SEUC236T5V4U

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

SEUC236T5V4U from ElecSuper, 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 | IO1 | passive | Connects to an I/O line for ESD and transient protection; the device is rated for a 5V peak reverse working voltage (VRWM) and clamps per IEC 61000-4-2 Level 4 (±12kV contact, ±17kV air). |
| 2 | GND | power_in | Connects to ground, which is the reference for the clamping paths of the I/O pins. |
| 3 | IO2 | passive | Connects to an I/O line for ESD and transient protection; the device is rated for a 5V peak reverse working voltage (VRWM) and clamps per IEC 61000-4-2 Level 4 (±12kV contact, ±17kV air). |
| 4 | IO3 | passive | Connects to an I/O line for ESD and transient protection; the device is rated for a 5V peak reverse working voltage (VRWM) and clamps per IEC 61000-4-2 Level 4 (±12kV contact, ±17kV air). |
| 5 | Vcc | power_in | Connects to the Vcc supply rail; the datasheet gives a 5V working voltage (VRWM) for the protected lines and no separate supply-range limit for this pin. |
| 6 | IO4 | passive | Connects to an I/O line for ESD and transient protection; the device is rated for a 5V peak reverse working voltage (VRWM) and clamps per IEC 61000-4-2 Level 4 (±12kV contact, ±17kV air). |
