Mounting Information

The

illustration

indicates

the

recommended

mounting

pad

configura t io n

for

the

SOT-23 package. Solder paste containing flux

should be screened onto the pads to a thickness of

0.005- 0.007 inches. The plastic package is placed

in position, firmly adhering to the solder paste.

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, for standard

models and +260

°C for the RoHS compliant

devices.

Please refer to Application Note M538 for surface

mounting instructions.
