Description : This is a small program to find transistor data. Not everything is listed (1442 different devices). Download a copy, place it into the directory of choice and run the program, which is a self extracting archive. There are two extracted files - ESP-TRAN.EXE and BIPOLAR.TXT, being the executable and database respectively. ESP-SEMI.EXE may be deleted after extraction unless you want to give a copy to someone else. New stuff can be added as you find the data. If you add a lot of stuff, feel free to e-mail me a copy of the new database (compressed, please!), and I will add it to the database file.
