CMXSTB400 TR PBFREE

Diode Arrays Overview

The Central Semiconductor CMXSTB400 TR PBFREE is a surface mount silicon forward reference diode (stabistor) housed in an SOT-26 package. It contains four internal diodes designed for applications requiring controlled forward voltage characteristics, such as voltage regulation, sensing, and comparing. The device serves as a surface mount alternative to the 1N5179 leaded device. Maximum ratings include a power dissipation of 350 mW and an operating junction temperature range from -65°C to +150°C. Electrical testing between Pin 1 and Pin 3 specifies a maximum reverse current of 10 µA at 20V.
