PCN1040A Laser Brand Transition Amendment to Correct and Clarify PCN1040

September 4, 2015

To Our Valued Customers:

The following is to update IXYS Integrated Circuits Division customers of the laser marking change. This

notification is part of our effort and commitment to continuous improvement of our processes and

products. IXYS Integrated Circuits Division’s quality system requires customer notification under the

circumstances outlined below.

IXYS Integrated Circuits Division’s notification policy states:

IXYS Integrated Circuits Division is mindful that changes to process or product could have an

adverse impact on our customers.

Therefore we verify, through our qualification methodology, that a change does not

negatively affect product quality or reliability. We also verify that it does not impact form, fit,

or function.

Changes to function are notified to the customer if the change could adversely affect the

customer but not if the change is to enhance product performance beyond the current

specification, for example, higher isolation voltage capability for Solid State Relays.

In cases where a planned change would impact form, fit, or would adversely affect function,

quality or reliability, we notify the customer 90 days in advance.

We also notify our customers of planned product obsolescence.

The following definitions apply:

Form: the visual appearance including color, marking, and surface finish

Fit: the external dimensions and associated tolerances

Function:

the

electrical,

mechanical,

thermal,

quality

and

reliability

performance

characteristics

IXYS Integrated Circuits Division notifies customers of the changes using a Product Change Notification

(PCN). Attached are the details of the pending product change.

Sincerely,

Steven Andrezyk
