NPN pre-biased (bias resistor built-in) transistor, 50 V VCEO, 100 mA, 200 mW. Internal network: R1 = 2.2 kΩ series resistor from BASE (input, pin 1) to transistor base; R2 = 47 kΩ from internal base to EMITTER (pin 2). S-Mini (SOT-346 / SC-59 / TO-236MOD, DigiKey: SOT-23-3) 3-pin. Pinout: 1 = B (input), 2 = E, 3 = C.
