UPS840e3 UPS840e3 Powermite 3 Surface Mount Compliant 8 Amp 40 Volt Schottky Rectifier DESCRIPTION The UPS840e3 offers an exceptionally small and powerful RoHS compliant package for a 40 V, 8 Amp Schottky rectifier. Competing solutions typically come only in much larger packages. It is an ideal, small footprint, surface mount solution with a full metallic bottom side and is compatible with automatic insertion equipment. In combination with Microsemi s unique internal locking tab on the die, it provides a very low thermal resistance path to move heat out of the package. The resulting lowering of junction temperature in the die provides for lower leakage current and power loss.

PART NOMENCLATURE UPS 8 40 e3 Powermite Schottky RoHS Compliance e3 = RoHS compliant Maximum Average Blank = non-RoHS compliant DC Output Current Maximum Peak Reverse Voltage SYMBOLS & DEFINITIONS Symbol Definition Total Capacitance: The total small signal capacitance between the diode terminals of a complete device. C T IF Forward Current: The forward current dc value, no alternating component. IFSM Maximum Forward Surge Current: The forward current, surge peak or rated forward surge current. Average Rectified Output Current: The output current averaged over a full cycle with a 50 Hz or 60 Hz sine-wave input IO and a 180 degree conduction angle. IR Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature. VF Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current. VR Reverse Voltage: The reverse voltage dc value, no alternating component. Repetitive Peak Reverse Voltage: The peak reverse voltage including all repetitive transient voltages but excluding all VRRM non-repetitive transient voltages. Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature range VRWM excluding all transient voltages (ref JESD282-B). Also sometimes known as PIV.
