he 2N7000 is a widely available and popular part, often recommended as useful and common components to have around for hobbyist use, along with such other popular discrete semiconductors as the 1N4148 and 1N4001 diodes; the 2N2222, 2N3904, and 2N3906 bipolar junction transistors; and the IRF510 power MOSFET.[2] The BS250P is “a good p-channel analog of the 2N7000.”
