A somewhat little know part is a "pre-biased transistor": this is a bipolar transistors with built-in resistors, and will often work as a drop-in replacement for a logic-level MOSFET (like 2n7000), but is an order of magnitude cheaper. https://www.digikey.com/en/products/detail/diotec-semiconductor/MMBTRC119SS/22189965 https://www.digikey.com/en/products/detail/diotec-semiconduc...
