DESCRIPTION
Thi s “stan dard rec overy” s urface moun t recti fi er diode seri es is mi lit ar y qualif i ed and i s ideal
for high-r el iability app l ication s where a f ailure cannot be t ol er ated. Th ese ind ustry-recognized
5.0 amp rated rect ifiers for working peak r everse volt ages from 200 to 1000 volts are
hermeti cally sealed wi th voidless -glas s construction using an in ternal “Category 1”
metallu r gical bond . Thes e devic es are also avai l able i n axia l -leaded pac kag es for thru-hole
moun ting. Micr osemi als o off er s n umerous other rec tifier produ cts t o meet h igher and lower
current ratings wi th various reco very time speeds .

MAXIMUM RATINGS
Notes: 1. De rate li near ly at 6 6. 6 mA/º C abo ve TEC = 100 ºC. An IO of up to 6 Amps is allowable provided that appropriate heat sinking or forced air
cooling maintains the junction temperature at or below +200 oC.
2. De rate li near ly at 22.2 mA/ºC from +55 ºC to +100 oC.
3. These IO ratings are for a thermall y (PC boards or other) mounting methods where the lead or end-cap tem peratures cannot be maintained
and where thermal resistance from mounting point to ambient is still sufficiently controlled where TJ(MAX) do es not exce ed 175 oC. This
equates to RθJX ≤ 47 ºC/W.
4. De rate li nearly at 26.7 mA/°C above TA= +100 °C to +175 ° C am bient .

SYMBOLS & DEF INITIONS

Definition
VBR
Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current.
VRWM
Worki ng Peak Reverse V oltage: The maximum peak vol tage 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 conduction angle.
VF
Maximum Forward Voltage: The maximum forward voltage the device will exhi bit at a specified current.
IR
Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified vol tage and
temperature.
trr
Reverse Recovery Time: The time interval between the instant the current passes through zero when changing from
the forward di rection to the reverse direction and a specified decay point after a peak reverse current occ urs.
