ESD0502EQ
Yangzhou Yangjie Elec Tech · ESD And Surge Protection (TVS/ESD) · SOT-23
ESD0502EQ from Yangzhou Yangjie Elec Tech, 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 | I/O1 | passive | Protected line 1 (diode cathode), 5V reverse stand-off (VRWM) with IEC61000-4-2 protection of ±30kV contact and ±30kV air, clamping to ground via the common pin. |
| 2 | I/O2 | passive | Protected line 2 (diode cathode), 5V reverse stand-off (VRWM) with IEC61000-4-2 protection of ±30kV contact and ±30kV air, clamping to ground via the common pin. |
| 3 | GND | power_in | Common anode of both diodes, connected to ground as the reference for the two uni-directional protected lines (RDYN is specified I/O to Ground). |
