The MM1Z27BW with SOD-123W Zener Diodes is a series of ROHS-compliant voltage regulators manufactured by Jingdao. The product is specifically designed for circuit protection and voltage regulation applications. This Zener Diode is constructed with two terminals, a cathode, and an anode. The diode’s case is composed of 4 terminal leads. The body size of the diode is small, which allows it to be integrated into many different circuit designs. The MM1Z27BW can provide overcurrent protection and voltage clamping. It also ensures the load voltage and current stability and ripple reduction. Moreover, the MM1Z27BW has a wide operating temperature range of -65°C to +175°C, making it the perfect choice for extreme temperature environments.
