Maximum Ratings:
• • • • max. electrical power dissipation max. optical peak value, once max. continous optical operation ( Pelectr. = Popt. * Sabs * M * UR ) 200 mW at 22°C 400 mW for 1 s IPh (DC) ≤ 500 µA ≤ 2 mA for signal 50 µs "on" / 1 ms "out"
Bias supply voltage
Current limiting resistor
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 min. Pin - length ESD - protection Storage 260°C for max. 10 s. The device must be protected against solder flux vapour! 2mm Only small danger for the device. Standard precautionary measures are sufficient. Store devices in conductive foam. 1999/07
