ABSOLUTE MAXIMUM RATINGS
DL-53X8AR
****************************************************************************************************************************************************************
Stress in excess of the absolute maximum rating can cause permanent damage to the device. These are absolute stress
rating only. Functional operation of the device is not implied at these or any other conditions in excess of these given in
the operational sections of the datasheet. Exposure to absolute ratings for extended periods can adversely affect device
reliability.

PRECAUTIONS for USE
1. ESD protection is imperative. Use of grounding straps, anti-static mats, and other ESD protective equipment is
recommended when handling or testing an any junction photodiodes.
2. Fiber pigtails should be handled with less than 10N pull and with a bending radius greater than 30 mm.
