S7516 series
S7516 series is a Si PIN photodiode incorporating a wide band preamplifier chip, hermetically sealed in a TO-8 package. The photodiode has a
large active area (
B3 mm) yet offers a wide bandwidth, making S7516 series suitable for spatial light transmission. A lens (B9 mm) window type
(S7516-01) is also available.

G ESD
S7516 series may be damaged or their performance may deteriorate by such factors as electro static discharge from the human body,
surge voltages from measurement equipment, leakage voltages from soldering irons and packing materials, etc. 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
).
A semiconductive sheet (1 M
to 100 M) 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
.
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
/cm2 to 1 G/cm2.
G Wiring
If electric current or voltage is applied in reverse polarity to an electronic device such as a preamplifier, this can degrade device performance
or destroy the device. Always check the wiring and dimensional
outline to avoid misconnection.
