Handling Precautions
Caution: This device is susceptible to damage as a result of electrostatic discharge (ESD). Take proper
precautions during both handling and testing. Follow guidelines such as JEDEC Publication No.
108-A (Dec. 1988).
Although protection circuitry is designed into the device, take proper precautions to avoid exposure to ESD.
Electrical/Optical Characteristics
* The slope efficiency is used to calculate the modulation current for a desired output power. This modulation current plus the threshold current
comprise the total operating current for the device.
Corrected for electrical pulse fall time.
