DESCRIPTION APPEARANCE
This “standard recovery” rectifier diode series is military qualified to MIL-PRF-
19500/420 and is ideal for high-reliability applications where a failure cannot be
tolerated. These industry-recognized 5.0 Amp rated rectifiers for working peak
reverse voltages from 200 to 1000 volts are hermetically sealed with voidless-glass
construction using an internal “Category I” metallurgical bond. These devices are
also available i n surface mount MELF packa ge configurations b y adding a “US” suffi x
(see separate data sheet for 1N5550US thru 1N5554US). Microsemi also offers
numerous other rectifier products to meet higher and lower current ratings with
various recovery time speed requirements in cluding fast and ultrafast device types in
both through-hole and surfac e mount packages.

NOTE 1: Rated at TL = 55ºC at L = 0.375 inch from body. Derate linearly at 41.6 mA/ºC above TL = 55ºC
NOTE 2: Derate linearly at 25 mA/ºC above TA = 55ºC. This rating is typical for PC boar ds where thermal resistance from
mounting point to ambient is sufficiently controlled where TJ(MAX) rating is not exceeded.

SYMBOLS & DEFINITI ONS
Symbol Definition
VBR Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current.
VRWM Working Peak Reverse Voltage: The maximum peak vo ltage that can be applied over the operating
temperature range excluding all transient voltages (ref JESD282-B).
IO 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 conductio n ang le.
VF Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
IR Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and
temperature.
trr 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.
