HESDA25L
HXY MOSFET · Electrostatic And Surge Protection (TVS/ESD) · SOT-23
HESDA25L 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 | Protected line (diode 1 anode side in the circuit diagram); working voltage 24V, protects one bidirectional line with pin 2 or two unidirectional lines against pin 3. |
| 2 | 2 | passive | Second protected line (diode 2 anode side in the circuit diagram); working voltage 24V, can protect a second unidirectional line against pin 3. |
| 3 | 3 | passive | Common node of the two diodes in the circuit diagram, shared reference for the two unidirectional channels on pins 1 and 2. |
