ZX0504B from XCH(旭昌辉), in a SOT-23-5. 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 | Protected I/O line (any I/O to ground: VRWM 5.0 V, clamping 10.8 V at IPP = 1 A and 15 V at IPP = 8 A, tp = 8/20 μs). |
| 2 | GND | power_in | Common ground/reference node of the TVS diode array, to which all I/O clamping voltages are referenced. |
| 3 | I/O2 | passive | Protected I/O line (any I/O to ground: VRWM 5.0 V, clamping 10.8 V at IPP = 1 A and 15 V at IPP = 8 A, tp = 8/20 μs). |
| 4 | I/O3 | passive | Protected I/O line (any I/O to ground: VRWM 5.0 V, clamping 10.8 V at IPP = 1 A and 15 V at IPP = 8 A, tp = 8/20 μs). |
| 5 | I/O4 | passive | Protected I/O line (any I/O to ground: VRWM 5.0 V, clamping 10.8 V at IPP = 1 A and 15 V at IPP = 8 A, tp = 8/20 μs). |
