CMXSTB300 BK PBFREE

Diode Arrays Overview

The Central Semiconductor Corp CMXSTB300 BK PBFREE is a surface mount silicon forward reference diode, also known as a stabistor. It belongs to the CMXSTB200 series and features three internal diodes mounted in an SOT-26 case. The device provides controlled forward voltage characteristics for applications requiring voltage regulation, sensing, and comparing. It serves as a surface mount alternative to leaded devices like the 1N4157. Electrical testing between Pin 1 and Pin 3 specifies a maximum reverse leakage current of 10 µA at 20V. Forward voltage ranges from 2.08V to 2.28V at 10mA test conditions.
