CD143A-SR05-HXY from HXY MOSFET, in a SOT-143. 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 | GND | power_in | Negative rail of the diode array, connected to system ground; positive ESD current is steered to it through an ESD diode and the zener diode. |
| 2 | IO1 | passive | ESD-protected I/O channel 1 with a pair of steering diodes to the rails, 0.4 pF typical capacitance to GND at VR=0V, 1MHz. |
| 3 | IO2 | passive | ESD-protected I/O channel 2 with a pair of steering diodes to the rails, 0.4 pF typical capacitance to GND at VR=0V, 1MHz. |
| 4 | VDD | power_in | Positive supply rail of the array, with the integrated zener diode to GND (VRWM 5 V, VBR 6 V min at 1 mA); positive ESD voltage is clamped to the zener voltage. |
