1 / 3 page  ULTRAFAST RECTIFIERS, High Efficiency, 50ATM SCOTTSD A L E DIVISION UES804 UES804HR2 UES805 UES805HR2 UES806 UES806HR2 DESCRIPTION APPEARANCE 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. DO-5 IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS • 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) • Power Switching Circuits 20 kHz and above with minimal parasitic switching losses • Catch Diodes for Switching Regulators • Output Rectifiers for High Frequency Square- Wave Inverters • Extremely Robust in Power Cycling • High Surge Capability • Hermetically Sealed ABSOLUTE MAXIMUM RATINGS MECHANICAL AND PACKAGING • Peak Inverse Voltage, UES804, UES804HR2……….200 V • Peak Inverse Voltage, UES805, UES805HR2……….300 V • Peak Inverse Voltage, UES806, UES806HR2……….400 V • Average DC Output Current, IO @ TC = 100 oC………50 A • Surge Current, 8.3 ms …………………………………600 A • Thermal Resistance, Junction to Case……………0.8 oC/W • Operating and Storage Temp.
