SL15.TCT
SEMTECH · ESD And Surge Protection (TVS/ESD) · SOT-23-3
SL15.TCT from SEMTECH, in a SOT-23-3. 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 | Pin 1 | passive | Connects to the protected high-speed line; it is one terminal of the series low-capacitance compensation diode and TVS pair, which reduces device capacitance to less than 5pF. |
| 2 | Pin 2 | passive | Connects to ground (or to a second line for differential protection) and is the opposite terminal of the internal diode pair from pin 1, rated for 15V reverse stand-off on the SL15 variant. |
| 3 | N.C. | unconnected | Pin 3 is not connected and is left unused in the one-line protection configuration. |
