DESCRIPTION
“A” Package
This “standard recovery” rectifier diode series is military qualified to MIL-PRF-19500/286
and is ideal for high-reliability applications where a failure cannot be tolerated. These
industry-recognized 1.0 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 similar in ratings to the 1N5614 thru
1N5622 series where surface mount MELF package configurations are available by adding a
“US” suffix (see separate data sheet for 1N5614US thru 1N5622US). Microsemi also offers
numerous other rectifier products to meet higher and lower current ratings with various
recovery time speed requirements including fast and ultrafast device types in both through-
hole and surface mount packages.

PACKAGE DIMENSIONS
NOTE:
1. Dimensions are in inches.
2. Millimeters are given for general information only.
3. Dimension BD shall be measured at the largest diameter.
4. The BL dimension shall include the entire body including slugs and
sections of the leads over which the diameter is uncontrolled. This
uncontrolled area is defined as the zone between the edge of the
diode body and extending .050 inch (1.27 mm) onto the leads
5. The shape of the body, within the bounds of the dimensions is
optional.
6. In accordance with ASME Y14.5M, diameters are equivalent
to
φx
symbology.
