Note 1.

Specification for packaged product only.

DC ELECTRICAL CHARACTERISTICS(Note 1)

Note 1.

Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation

is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM

RATlNG conditions for extended periods may affect device reliability.

Note 2.

The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.

Note 3.

The device is guaranteed to meet the DC specifications, shown in the table above, after thermal equilibrium has been established. The device

is tested in a socket such that transverse airflow of

≥500lfpm is maintained.

Note 4.

The voltage drop across REXT and RSER plus Laser Diode must not be greater than 2.3V.

Note 5.

Commercial devices are guaranteed from 0

°C to +85°C ambient temperature.
