Description

The BUX87 is a silicon NPN high voltage switching transistor made by IPRS Băneasa [1].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the BUX87 and BUX87/9 (preliminary data) among the „High voltage switching transistors – plastic case” of its „High power” section [1]. Their values are under Variants [1].
