71. Transistor Part Selection

Question.10

Hardware Developer is selecting an NPN transistor to switch a 12 V relay coil drawing 75 mA from a 3.3 V MCU GPIO. The transistor is in low-side configuration with the relay coil between +12 V and the collector.

The design requires:

NPN BJT, V_CEO ≥ 30V, I_C(max) ≥ 200mA, h_FE ≥ 100 at I_C = 100mA, SOT-23 SMD

He chooses the ZXTP19060CFFTA (Diodes Inc).

Is this the correct component for the given requirement?
