UMW · ESD And Surge Protection (TVS/ESD) · SOT-23
SM36-02HTG from UMW, 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/O 1 | bidirectional | Protected line; the datasheet rates it for ESD (IEC 61000-4-2 ±30 kV contact and air) and 8/20 µs surge clamping measured from pin 1 to pin 3. |
| 2 | I/O 2 | bidirectional | Protected line; the datasheet rates it for ESD (IEC 61000-4-2 ±30 kV contact and air) and 8/20 µs surge clamping measured from pin 2 to pin 3. |
| 3 | GND | power_in | Common reference terminal; all clamp and ESD test conditions are specified as pin 1 or pin 2 to pin 3, and the I/O-to-GND capacitance is referenced to it. |
