Zener (1N5231C)
1N5231C Rev. C1
2004 Fairchild Semiconductor Corporation
Absolute Maximum Ratings* TA = 25°C unless otherwise noted T olerance = 2%
Electrical Characteristics TA = 25°C unless otherwise noted
NOTES:
1) These ratings are based on a maximum junction temperature of 200 degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed
or low duty cycle operations.
*These ratings are limiting values above which the serviceability of the diode may be impaired.
**Non-recurrent square wave PW= 8.3 ms, T A= 50 degrees C.

failure to perform when properly used in accordance
with instructions for use provided in the labeling, can be
reasonably expected to result in significant injury to the
user.
2. A critical component is any component of a life
support device or system whose failure to perform can
be reasonably expected to cause the failure of the life
support device or system, or to affect its safety or
effectiveness.
