S9018-H

Shandong Jingdao Microelectronics · Bipolar (BJT) · SOT-23

S9018-H from Shandong Jingdao Microelectronics, 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 BASE passive Base terminal of the NPN transistor; the datasheet's emitter-base rating VEBO is 5.0 Vdc maximum, with emitter-base breakdown V(BR)EBO of at least 5.0 Vdc.
2 EMITTER passive Emitter terminal of the NPN transistor; emitter-base voltage VEBO is limited to 5.0 Vdc and emitter cut-off current IEBO is 0.1 uAdc maximum at VEB = 3 Vdc.
3 COLLECTOR passive Collector terminal of the NPN transistor; ratings are VCEO 15 Vdc, VCBO 30 Vdc and continuous collector current IC 50 mAdc, with total device dissipation PD 200 mW.
