These are ALJ 2302 MOSFETs. The ALJ 2302 is an N-channel power MOSFET in a breadboard-friendly TO-92 package with reasonable specifications for the price. They have a typical Rds(on) of 70 mΩ at a gate voltage of 2.5 V and 45 mΩ at 4.5 V which makes them less efficient than the other logic-level MOSFETs I sell, but they are the best option I have found in a breadboard-friendly TO-92 package (which seems to be quite an uncommon package for MOSFETs) and equivalent in efficiency to my competitor's TO-220 logic-level MOSFETs which don't even have a specified Rds(on) below 5 V.

If your switching needs are not too demanding then these are a convenient prototyping solution but if you require more power or higher efficiency, please check out my favourite logic-level MOSFETs in TO-220 package.

The breadboard in the photograph is intended to convey the breadboard-friendly leads (they will not damage the spring contacts of the breadboard). The breadboard is not included in the sale.
