KRA102S-RTK from KEC Semicon, 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 | COMMON (EMITTER) | passive | Common emitter terminal of the built-in bias-resistor PNP transistor; the datasheet gives no separate voltage or current limit for this pin beyond the family absolute maximum ratings. |
| 2 | IN (BASE) | input | Base input with built-in bias resistors; for KRA102S the input voltage is rated -30 V to 10 V, and the input current is rated at most -0.88 mA at VI = -5 V. |
| 3 | OUT (COLLECTOR) | output | Collector output of the PNP transistor; the family output voltage is rated -50 V maximum and output current -100 mA maximum. |
