DO-4
The UES704 series of ultrafast high-efficiency rectifiers is specifically
designed for operation in power switching circuits operating at frequencies
of 20 kHz or higher. The low thermal resistance and forward voltage drop
of this series allows the user to replace DO-5 size devices in many
applications. These devices have also been demonstrated capability in
passing power-stress testing to 25 thousand cycles with full-rated forward
current turned on and off without a heat sink. This forces case temperature
increases of 75 °C at which time the current is removed to simulate worst
case applications. The switching times increase relatively little with
temperature or at different currents.
