SM36T1G

DOWO · ESD And Surge Protection (TVS/ESD) · SOT-23

SM36T1G from DOWO, 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 PIN1 passive Protected line terminal of the bidirectional TVS, rated for a reverse working voltage of 36 V and a junction capacitance of 12 to 16 pF to PIN3 at 0 V and 1 MHz.
2 PIN2 passive Protected line terminal of the bidirectional TVS, rated for a reverse working voltage of 36 V and a junction capacitance of 12 to 16 pF to PIN3 at 0 V and 1 MHz.
3 PIN3 passive Common terminal of the bidirectional TVS, referenced by the PIN1/PIN2 capacitance specification, with the device rated at 360 W peak pulse power (tp = 8/20 µs) and ±30 kV ESD contact/air per IEC 61000-4-2.
