2N7000

The 2N7000 and BS170 are two different N-channel, enhancement-mode MOSFETs used for low-power switching applications, with different lead arrangements and current ratings. They are sometimes listed together on the same datasheet with other variants 2N7002, VQ1000J, and VQ1000P. The 2N7000 is a widely available and popular part, often recommended as useful and common components to have around for hobbyist use.The BS250P is "a good p-channel analog of the 2N7000."
