SZNUP2115LT1G

onsemi · ESD And Surge Protection (TVS/ESD) · SOT-23-3

SZNUP2115LT1G from onsemi, 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 CATHODE passive Pin 1 is a diode cathode terminal per the package outline Style 27 (CASE 318-08) listed for this device; the datasheet gives no electrical limit for this pin individually and does not state whether it is a line or GND connection.
2 CATHODE passive Pin 2 is a diode cathode terminal per the package outline Style 27 (CASE 318-08) listed for this device; the datasheet gives no electrical limit for this pin individually and does not state whether it is a line or GND connection.
3 CATHODE passive Pin 3 is a diode cathode terminal per the package outline Style 27 (CASE 318-08) listed for this device; the datasheet gives no electrical limit for this pin individually and does not state whether it is a line or GND connection.
