SURFACE MOUNT SILICON
FORWARD REFERENCE DIODE
(STABISTOR)
DESCRIPTION:
The CENTRAL SEMICONDUCTOR CMXSTB200 Series
types are multi-chip silicon diodes mounted in a surface
mount SOT-26 case and designed for applications
requiring controlled forward voltage characteristics such
as voltage regulation, sensing, and comparing. This
series is a surface mount alternative to the 1N4156,
1N4157, and 1N5179 leaded devices, respectively.
Special selections of DC parameters including VF at
various test conditions are available on special order.
