HESDB24C-AQ from HXY MOSFET, in a SOT-23. 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 | Diode terminal on the left of the circuit diagram, tied through its diode to common pin 3; the part gives IEC61000-4-2 ESD protection of ±30 kV air and ±30 kV contact. |
| 2 | 2 | passive | Diode terminal on the right of the circuit diagram, tied through its diode to common pin 3; the working voltage is 24 V max (VRWM) with 0.5 µA max leakage. |
| 3 | 3 | passive | Common node joining both diodes in the circuit diagram, with a breakdown voltage of 26 V min to 33 V max at 1 mA and a peak pulse power of 160 W (8/20 µs). |
