SR05-02CTG-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 ESD array, connected to system ground; positive ESD current is steered to it through an ESD diode and the Zener diode. |
| 2 | I/O1 | passive | Protected I/O channel 1 with a pair of steering diodes to the rails, 0.4 pF typ. capacitance to GND and clamping voltage 14.0 V max at IPP = 1 A (8/20μs). |
| 3 | I/O2 | passive | Protected I/O channel 2 with a pair of steering diodes to the rails, 0.4 pF typ. capacitance to GND and clamping voltage 14.0 V max at IPP = 1 A (8/20μs). |
| 4 | VDD | power_in | Positive rail of the ESD array, with the Zener diode to GND (VRWM 5 V max, VBR 6 to 8.5 V at 1 mA) and clamping voltage 14.0 V max at IPP = 9 A (8/20μs). |
