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
• Extremely Robust in Power Cycling
• High Surge Capability
• Hermetically Sealed
