Electrical and Mechanical Specifications
The absolute maximum ratings of the quad mixer Schottky diodes
are provided in Table 2. Electrical specifications are provided in
Table 3.
Associated SPICE model parameters are provided in Table 4.
Typical forward voltage characteristics are shown in Table 5.
Dimensions for the SOT-143 package are shown in Figure 1, and
tape and reel dimensions are provided in Figure 2.
Package and Handling Information
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The quad mixer Schottky diodes are rated to Moisture Sensitivity
Level 1 (MSL1) at 260 C for 5 seconds. They can be used for
lead or lead-free soldering. For additional information, refer to the
Skyworks Application Note, Solder Reflow Information, document
number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
