Hello there,

Isn't this the part you're looking for? https://www.snapeda.com/parts/2SK30A/avi/view-part/

Please be careful on using it as it was a user-generated part and it's not been verified.

You can also use these other N-channel transistors with TO-92 packages here: https://www.snapeda.com/search/?q=n-channel+transistor+TO-92&SEARCH=Search&sort=&resistance=&tolerance=&manufacturer=&package=&search-type=parts

Let me know if you need any help with anything else.
