This means that at a collector current of 0.3 µA, it only takes a base current of about 1 nA to saturate it, and this is much smaller than the specified base-emitter leakage current (I EBO = 100 nA). I''d say that at these current levels, a BJT is probably not your best choice. Consider using a low-leakage MOSFET instead.
