DESCRIPTION APPEARANCE
This “Ultrafast Recovery” rectifier diode series is ideal for high-reliability
applications where a fail ure cann ot be tol era ted. T hese 3, 6, and 12 Amp rated
rectifiers (TEC =70ºC) in different package sizes with working peak reverse
voltages from 50 to 150 volts are hermetically sealed using voidless-glass
construction and an internal “Category I” metallurgical bond. These devices
are also available in axial-lead package configurations for through-hole
mounting by deleting the “US” suffix (see separate data sheet for 1N6073 thru
1N6081). Microsemi also offers numerous other rectifier products to meet
higher and lo wer current rati ngs with various recovery time spee d requ irem ents
including standard, fast and ultrafast device types in both through-hole and
surface mount packages.
