HXYSLVU2.8-4

HXY MOSFET · ESD And Surge Protection (TVS/ESD) · SOP-8

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.
