FEATURES

=> Designed for use with TWT and Klystron switching power supplies. => Discretes and assemblies can be screened to TXV levels. => High Reverse Transient Energy capabilities. =» Void-free, hermetically sealed, metallurgically bonded discretes. => Single junction discretes provide superior thermal properties than designs using multi junction discretes. => Isolated Aluminum heat sink with Boron Nitride encapsulation provides superior power dissipation. =p All internal devices are matched 198% for avalanche BVR, IR, and trr. =» Unique construction techniques guarantee 1@8% corona free operation. =p Consult factory for higher voltages and currents and alternate bridge configurations.
