ESDU5V0H4 from UMW, in a SOT-23-6. 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 | bidirectional | I/O line 1; uni-directional TVS clamp between this pin and GND; reverse stand-off voltage 5 V, clamping voltage ≤15 V at IPP=1 A, junction capacitance 0.8 pF max (VR=0 V, f=1 MHz). |
| 2 | IO2 | bidirectional | I/O line 2; uni-directional TVS clamp between this pin and GND; same ratings as IO1: VRWM=5 V, VC≤15 V at IPP=1 A, CJ≤0.8 pF. |
| 3 | GND | power_in | Ground reference; common cathode/anode return for all four uni-directional TVS clamp channels; IEC 61000-4-2 ESD voltage (I/O to GND) ±25 kV. |
| 4 | IO3 | bidirectional | I/O line 3; uni-directional TVS clamp between this pin and GND; VRWM=5 V, VC≤15 V at IPP=1 A, CJ≤0.8 pF. |
| 5 | VCC | power_in | Supply-rail clamp pin; TVS protection from VCC to GND; breakdown voltage 5.8-8.1 V (IT=1 mA), clamping voltage ≤15 V at IPP=1 A, IR≤1 µA at VRWM=5 V. |
| 6 | IO4 | bidirectional | I/O line 4; uni-directional TVS clamp between this pin and GND; VRWM=5 V, VC≤15 V at IPP=1 A, CJ≤0.8 pF, I/O-to-I/O capacitance 0.4 pF typ. |
