Description

The BUW24 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 BUW24 (preliminary data) among the „High voltage switching transistors – metal case” of its „High power” section [1], with Ptot 100 W (TC = 25 °C), TJM 150 °C, VCES 450 V, VCEO 350 V, IC 10 A, VCEsat ≤ 1.5 V (IC = 2.5 A), hFE 10 (IC = 1 A, VCE = 5 V), ton ≤ 0.5 µs, ts ≤ 2 µs, tf ≤ 0.5 µs, TO-3d case [1].
