SM15-02HTG
UMW · ESD And Surge Protection (TVS/ESD) · SOT-23
SM15-02HTG 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/O1 | bidirectional | Protected signal line that is clamped to pin 3 by the SM15 TVS array, rated for ±30 kV contact and air ESD per IEC 61000-4-2 and 50 A EFT per IEC 61000-4-4 (5/50 ns). |
| 2 | I/O2 | bidirectional | Protected signal line that is clamped to pin 3 by the SM15 TVS array, rated for ±30 kV contact and air ESD per IEC 61000-4-2 and 50 A EFT per IEC 61000-4-4 (5/50 ns). |
| 3 | GND | power_in | Common reference terminal to which pins 1 and 2 are clamped; the electrical tables test I/O-to-GND and 'Pin 1 or Pin 2 to Pin 3' conditions. |
