The BZT52B33S is a Zener diode with SOD-323 RoHS package by Formosa. It is a 4-terminal device that has a voltage guard in order to protect high-voltage circuits. It is designed to effectively provide voltage-stabilization and enables over-voltage protection. It can provide reverse bias protection, high stability, and low reverse leakage current. It is optimized to perform with a power dissipation of 200mW, 5.6V breakdown voltage, and as low as 1mA reverse current. It is constructed with a copper-nickel soldered tab for improved durability and is ideal for applications such as voltage regulation, switching regulators, and general protection of circuits. It is manufactured with RoHS compliant materials and is ideal for applications that need to conform to environmental standards.
