This datasheet is subject to change without notice.

THE PRODUCT DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000

Notes:

a. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum (- 40 °C to 85 °C).

b. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing and are measured at VCC = 12 V unless otherwise

noted.

c. Gain is defined by A = DVCOMP/DVCS, 0 V

 VCS  0.8 V.

d. Start, Stop, and Zener voltages track each other.
