Protecting Diode Lasers from Electro-Static Discharge 
How to handle LD-PD’S laser diodes
|
Notice 1. Protecting Diode Lasers from Electro-Static Discharge (ESD) 2. Stress Greater than those listed under”ABSOLUTE MAXIMUM RATINGS” may cause permanent damage to this LD;these are stress ratings only and functional operational of the device at these or any other condition beyond those indicated for extend periods of time may effect device reliability. |
