UES2601(HR2) – UES2603(HR2)
HIGH EFFICIENCY RECTIFIERS
30 A Center-Tap
DESCRIPTION
This series of UES2601 through UES2603 combines two high efficiency devices into one
package, simplifying installation, reducing heat sink requirements and the need to purchase
matched components. Microsemi also offers numerous other products to meet higher and
lower power voltage regulation applications.

SYMBOLS & DEFINITIONS
Definition
Forward Current: The forward current dc value, no alternating component.
Maximum Peak Forward Current: The peak total value of the forward current dc value.
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 and a 180 degree conduction angle.
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature.
Reverse Recovery Time: The time interval between the instant the current passes through zero when changing from
the forward direction to the reverse direction and a specified decay point after a peak reverse current occurs.
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
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
non-repetitive transient voltages.
