1. SCOPE
* 1.1 Scope. This specification covers the performance requirements for silicon, general purpose, semiconductor
diodes. Four levels of product assurance are provided for each encapsulated device type as specified in
MIL-PRF-19500. Two levels of product assurance are provided for each unencapsulated device type.
1.2 Physical dimensions. See figure 1 (similar to DO-41) for 1N5550 through 1N5554, figure 2 for 1N5550US
through 1N5554US, and figures 3, 4, 5, 6, and 7 for JANHC and JANKC die.
1.3 Maximum ratings. Unless otherwise specified, T
C
= +25°C and ratings apply to all case outlines.

Notes
NOTES:
1.
Dimensions are in inches.
2.
Millimeters are given for general information only.
3.
Dimensions BL and BD include all components of the diode periphery
except the sections of leads over which the diameter is controlled.
4.
Dimension BD shall be measured at the largest diameter.
5.
Dimension LU shall include the sections of the lead 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.
6.
In accordance with ASME Y14.5M, diameters are
equivalent to
φx
symbology.
