Mounting Information

The illustration indicates the recommended mounting pad

configuration for the SOT-23, SOT-323 , SOD-323,

SOT-143, and SC-79 packages. Solder paste containing

flux should be screened onto the pads to a thickness of

0.005- 0.007 inches.

The plastic package device is

placed in position, firmly adhering to the solder past.

Permanent attachment is performed by a reflow soldering

procedure during which the tab temperature does not

exceed +275

°C and the body temperature does not

exceed +250

°C.

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.
