LMC10 Mounting Guidelines

The device must be attached to a heat-sink capable of

dissipating a minimum of 4W. The surface of the heat-sink

must be smooth (< 0.8 micron Ra) and flat (< 24.8 microns

over the area and not convex in form). Attachment screws,

thermal interface compounds or interface pads may be used

but must not exert stress upon the device. Refer to Bookham

applications document AN0117.

Note on Maximum Ratings and Handling Precautions

Applications Support

The following application notes are available to support customers using the LMC10NEJ:

It is the nature of this device that unprotected semi-conductor

junctions are connected directly to external package pins.

Protection of these junctions would have an adverse effect on

the performance of the device or the flexibility in its

application and use. The user is requested to observe the

‘Absolute Minimum and Maximum Ratings’ in order to

prevent damage or destruction of the device. In particular

forward biasing the modulator, attenuator or power monitor

junctions will lead to catastrophic damage if the current or

voltage limits are exceeded. These junctions are also sensitive

to ESD and electrical transients. The laser is similarly sensitive

to reverse bias, ESD and electrical transients. These can lead

to catastrophic device damage. The user is requested to

ensure that operation of any control or bias circuits do not

introduce electrical transients or adverse bias conditions

during switch-on, switch-off or calibration and set-up

routines. Appropriate ESD precautions are required in both

production and R&D environments.
