ROHM Semicon · Bipolar (BJT) · TO-236-3(SOT-23-3)
2SB1690KT146 from ROHM Semicon, in a TO-236-3(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 | Emitter | passive | Emitter lead; the datasheet's absolute maximum ratings are VEBO −6 V and IC −2 A continuous (−4 A pulsed, single pulse Pw=1ms) for the device. |
| 2 | Base | passive | Base lead; the datasheet gives VCE(sat) ≤ −180 mV at IC = −1 A / IB = −50 mA and DC current gain hFE of 270 to 680 at VCE = −2 V, IC = −200 mA. |
| 3 | C | passive | Collector lead; the datasheet's absolute maximum ratings are VCBO −15 V, VCEO −12 V, IC −2 A continuous (−4 A pulsed), and PC 200 mW. |
