ESD0502TL
MDD Microdiode Semiconductor · ESD And Surge Protection (TVS/ESD) · SOT-23
ESD0502TL from MDD Microdiode Semiconductor, 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 | ESD-protected high-speed data line 1 (I/O), with 0.2pF typical I/O-to-I/O capacitance and 5.0V max reverse working voltage to GND. |
| 2 | I/O2 | passive | ESD-protected high-speed data line 2 (I/O), with 0.2pF typical I/O-to-I/O capacitance and 5.0V max reverse working voltage to GND. |
| 3 | GND | power_in | Ground reference of the TVS/ESD protection circuit; I/O-to-GND reverse working voltage is 5.0V max and breakdown is 6.0V min at 1mA. |
