DISCLAIMER: The information given in this document shall in no event be regarded as a guarantee of conditions or characteristics. With respect

to any examples or hints given herein, any typical values stated herein and/or any information regarding the application of the device, Silicon Supplies

Ltd hereby disclaims any and all warranties and liabilities of any kind.

LIFE SUPPORT POLICY: Silicon Supplies Ltd components may be used in life support devices or systems only with the express written

approval of Silicon Supplies Ltd, if a failure of such components can reasonably be expected to cause the failure of that life support device or system

or to affect the safety or effectiveness of that device or system. Life support devices or systems are intended to be implanted in the human body or to

support and/or maintain and sustain and/or protect human life. If they fail, it is reasonable to assume that the health of the user or other persons may

be endangered.

1. Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended periods, may

reduce device reliability. 2. Assembled in DO-35 package. Performance in die form subject to assembly heat sinking and die attach methods.

3. VZ(reg) = VZ @ 50% of IZM minus VZ @ 10% of IZM 4. Zener impedance is derived by superimposing on lZT a 60Hz rms AC current equal to 10% of lZT

5. 1-3 kHz
