# ZX0511P

**XCH(旭昌辉)** · IC · DFN1006-2L

ZX0511P from XCH(旭昌辉), in a DFN1006-2L. 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 | 1 | passive | Terminal 1 of the bidirectional TVS diode (5.0V stand-off, 5.5V min breakdown at 1mA), connected to the protected line; the pin 1 index is marked on the bottom view. |
| 2 | 2 | passive | Terminal 2 of the bidirectional TVS diode (5.0V stand-off, 5.5V min breakdown at 1mA), connected to the protected line or ground; the diode symbol is symmetric so either polarity works. |
