The BU208A is a high voltage fast-switching NPN power transistor manufactured by STMicroelectronics using Multiepitaxial Mesa technology with a Hollow Emitter structure to enhance switching speeds.
Key electrical specifications include a collector-emitter sustaining voltage (VCEO(sus)) of 700V, a maximum collector current of 8A (15A peak), and a total power dissipation of 150W at 25°C case temperature. The device offers a transition frequency of 7 MHz and typical inductive load storage time of 7 µs with fall time of 550 ns.
The transistor is housed in a TO-3 (TO-204AA) metal package designed for chassis mount installation. It supports an operating junction temperature range up to 175°C and has a thermal resistance junction-to-case of 1°C/W.
This device is suitable for horizontal deflection circuits in color televisions and other high voltage switching applications requiring fast switching performance.
