LEAD MATERIAL: Copper clad steel
POLARITY: Cathode end is banded.
PACKAGE WEIGHT: 0.150g
U & US DESIGN DATA
CASE: D5D, Hermetically sealed glass
case, per MILPRF19500/578 & /609
LEAD FINISH: Tin/Lead
END CAP MATERIAL (U, US): Copper
POLARITY: Cathode end is banded.
PACKAGE WEIGHT: 0.095g
MOUNTING SURFACE SELECTION: The
Axial Coefficient of Expansion (COE) of this
device is approximately +4PPM/°C. The
COE of the Mounting Surface System
should be selected to provide a suitable
match with this device.
NOTES:
1. Dimensions are in inches. Millimeters are given for general information only.
2. Dimension BD shall be measured at the largest diameter.
3. The specified lead diameter applies in the zone between .050 inch (1.27 mm)
from the diode body to the end of the lead. Outside of this zone lead shall not exceed BD.
4. In accordance with ASME Y14.5M, diameters are equivalent to Φx symbology.
5. Usuffix parts are structurally identical to the USsuffix parts.
