# DRTR5V0U4S-7

**UMW** · ESD And Surge Protection (TVS/ESD) · SOT-363

DRTR5V0U4S-7 from UMW, in a SOT-363. 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 | CH1 | bidirectional | ESD-protected channel 1 line, rated per the datasheet for IEC 61000-4-2 contact discharge of ±8kV and air discharge of ±15kV, with 5A peak pulse current (8/20µs). |
| 2 | GND | power_in | Ground reference pin for the ESD clamps; the datasheet measures channel capacitance and reverse breakdown relative to this pin. |
| 3 | CH2 | bidirectional | ESD-protected channel 2 line, rated per the datasheet for IEC 61000-4-2 contact discharge of ±8kV and air discharge of ±15kV, with 5A peak pulse current (8/20µs). |
| 4 | CH3 | bidirectional | ESD-protected channel 3 line, rated per the datasheet for IEC 61000-4-2 contact discharge of ±8kV and air discharge of ±15kV, with 5A peak pulse current (8/20µs). |
| 5 | VDD | power_in | Supply/reference pin of the device shown as VDD in the pinning diagram; the datasheet gives a reverse standoff voltage of 6V (VRWM) for the protected lines. |
| 6 | CH4 | bidirectional | ESD-protected channel 4 line, rated per the datasheet for IEC 61000-4-2 contact discharge of ±8kV and air discharge of ±15kV, with 5A peak pulse current (8/20µs). |
