   Help with identifying a TO-92 transistor?(at least I think it’s a   
   transistor…)   
      
   Pretty vanilla-looking with National Semi logo. Marked:   
      
   NS 444   
   ST   
   13903   
      
   (The “NS” is the logo.)   
      
   Not enough 4’s to make up a standard 2N number, and 13903 looks like a date   
   code?   
      
   Ideas?   
      
   Thanks,
