Si photodiode with preamp

S9295 series

Cat. No. KSPD1064E01

Dec. 2004 DN

Precautions for use

s ESD

S9295 series may be damaged or their performance may deteriorate by such factors as electro static discharge from the

human body, surge voltage from measurement equipment, leakage voltages from soldering irons and packing materials. As a

countermeasure against electro static discharge, the device, operator, work place and measuring jigs must all be set at the

same potential. The following precautions must be observed during use:

•To protect the device from electro static discharge which accumulate on the operator or the operator

,

s clothes, use a wrist

strap or similar tools to ground the operator

,

s body via a high impedance resistor (1 M

Ω).

•A semiconductive sheet (1 M

Ω to 10 MΩ) should be laid on both the work table and the floor in the work area.

•When soldering, use an electrically grounded soldering iron with an isolation resistance of more than 10 M

Ω.

•For containers and packing, use of a conductive material or aluminum foil is effective. When using an antistatic material, use

one with a resistance of 0.1 M

s Strength

Thermoelectrically-cooler devices may be damaged if subjected to shock, for example drop impact. Take sufficient care

when handling these devices.

s Lead forming

When forming the leads, take care not to apply excessive force to the lead sealing glass. Excessive force may impair the

hermetic sealing, possibly degrading the cooling capacity.

To form the leads, hold the roots of the leads securely with a pair of pliers and bend them.

s Heatsink

Use a heatsink with thermal resistance less than 1.3 °C/W. Apply thermal grease between the heatsink and detector

package, and then fasten them with the screws. Be careful not to give any excessive force or mechanical stress to the

detector package at this point.

s Wiring

• Be careful not to misconnect the plus and minus leads of the thermoelectric cooler or preamplifier. Supplying a voltage or

current while these connections are reversed may damage the device.

• The feedback resistor integrated into S9295 series is high so it is susceptible to external noise. Always ground the case

terminal when using S9295.
