SMUN5235T1G

onsemi · Digital Transistors · SC-70-3

SMUN5235T1G from onsemi, in a SC-70-3. 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 BASE input Base (input) of the NPN bias resistor transistor, connected through series resistor R1 = 2.2 kΩ, with input forward voltage max 12 Vdc and reverse voltage max 6 Vdc.
2 EMITTER power_in Emitter (ground) of the transistor, connected to the base through R2 = 47 kΩ (R1/R2 ratio 0.047 typ).
3 COLLECTOR output Collector (output) with VCEO max 50 Vdc, VCBO max 50 Vdc and continuous collector current max 100 mAdc.
