PIN Diode Cross Reference
Many of M/A-COM’s glass axial lead hermetic surface mount
and plastic PIN diodes use similar chips and, therefore, have the
same electrical characteristics, except for package parasitics.
The following table lists the SOT-23, SOT-323 and SOD-323
PIN diodes by model number and standard axial lead PIN diode
and the equivalent square surface mount (SMQ) PIN diodes.
Mounting Information
The illustration indicates the recommended mounting pad con-
figuration for the SOT-23, SOT-323 and SOD-323 packages.
Solder paste containing flux should be screened onto the pads to
a thickness of 0.005 inches.
The plastic package device is
placed in position, firmly adhering to the solder past.
Permanent attachment is performed by a reflow soldering proce-
dure during which the tab temperature does not exceed +275
°C
and the body temperature does not exceed +250
°C.
