DESCRIPTION
APPEARANCE
DO-5
The UES804 series of ultrafast high-efficiency rectifiers is specifically
designed for operation in power switching circuits operating at frequencies
of 20 kHz or higher. These devices have 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.
IMPORTANT:
