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.

† BOL value; EOL = 80 mA.

‡ 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.

§ VR = reverse voltage.
