The 2ST15300 is a power bipolar transistor able to operate under severe environment conditions and radiation exposure. It offers high reliability performance and immunity to the total ionizing dose (TID) up to 100 krad. Qualified as per 5201/020 ESCC specification and available in SMD.5 hermetic package, it is specifically recommended for space and harsh environment applications and suitable for satellite electrical propulsion, inductive load switches and linear amplifiers. In case of discrepancies between this datasheet and the relevant agency specification, the latter takes precedence.
