Maximum Ratings:

•

max. electrical power dissipation

100 mW at 22°C

•

max. optical peak value, once

200 mW for 1 s

•

max. continous optical operation

≤ 250 µA

≤ 1 mA for signal 50 µs "on" / 1 ms "out"

•

Application hints:

•

Current limit is to be realized via protecting resistor or current limiting - IC inside the

supply voltage.

•

Use of low noise read-out - IC.

•

For higher gain a regulation of bias voltage due to the temperature is to be realized.

•

For very small signals stray light (noise source) is to be excluded by filters in order to

improve the signal-noise relation.

•

Avoid touching the window with fingers!

•

Careful cleaning with Ethyl alcohol possible.

•

Avoid use of pointed and scratching tools!

Handling precautions:

•

Soldering temperature

260°C for max. 10 s. The device must be protected against solder flux vapour!

•

min. Pin - length

2mm

•

ESD - protection

Only small danger for the device. Standard precautionary measures are sufficient.

•

Storage

Store devices in conductive foam.
