CMXSTB200 CMXSTB300 CMXSTB400 w w w. c e n t r a l s e m i . c o m 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.
