DESCRIPTION

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.

FEATURES

• Very Low Forward Voltage

• Very Fast Recovery Times

• High Reliability Screening Options with HR2 Suffix (ie. UES804HR2)

• Low Thermal Resistance

• Mechanically rugged

• Standard Polarity is Cathode to Case. For Reverse Polarity, Add Suffix R (ie. UES804R)

APPLICATIONS / BENEFITS

• Power Switching Circuits 20 kHz and above with minimal parasitic switching losses

• Catch Diodes for Switching Regulators

• Output Rectifiers for High Frequency SquareWave Inverters
