Central CMXSTB200 CMXSTB300 CMXSTB400 TM Semiconductor Corp. DESCRIPTION: The CENTRAL SEMICONDUCTOR CMXSTB 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 SURFACE MOUNT FORWARD REFERENCE DIODE (STABISTOR) available on special order.
