HXYSLVU2.8-4 from HXY MOSFET, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | passive | Protected I/O line 1. Steering diodes clamp transients to GND rail; VRWM = 2.8V, VBR ≥ 3.0V @ 2µA, VC ≤ 8.5V @ IPP = 5A. Junction capacitance ~2pF (VR = 0V, 1MHz). |
| 2 | GND | power_in | Ground / reference rail return. Common cathode / anode node for the steering + TVS clamp diodes; connect via short, low-inductance trace directly to system ground for effective ESD clamping. |
| 3 | I/O2 | passive | Protected I/O line 2. Steering diodes to GND; VRWM = 2.8V, VC ≤ 8.5V @ 5A (8/20µs). Low 2pF loading suitable for high-speed data lines. |
| 4 | GND | power_in | Ground / reference rail return (shared with pin 2). Provides low-impedance return path for ESD strike currents to be clamped by the internal TVS diode. |
| 5 | GND | power_in | Ground / reference rail return (shared with pins 2/4/7). Bond to solid ground plane; the GND pins are internally tied through the central TVS clamp diode network. |
| 6 | I/O3 | passive | Protected I/O line 3. Steering diodes to GND; VRWM = 2.8V, VBR ≥ 3.0V, VC ≤ 8.5V @ 5A pulse. Insert in series with the protected signal at the connector side. |
| 7 | GND | power_in | Ground / reference rail return (shared with pin 5). Common node for the central bidirectional TVS clamp diode. |
| 8 | I/O4 | passive | Protected I/O line 4. Steering diodes to GND; VRWM = 2.8V, VC ≤ 8.5V @ 5A (8/20µs), CJ ≈ 2pF. Place as close to the connector / edge of PCB as possible. |
