The BZT52C36 with Zener Diodes SOD-123 RoHS manufactured by Formosa is a 3-terminal zener diode. It has a maximum power dissipation of 500mW and a working voltage range of 3.1V - 76V. It features low inductance, fast switching capabilities, a wide and flat VZ tolerance, and is compliant with RoHS/REACH directives. The device is constructed with a hermetic sealed ceramic body and incorporates a special processing technique for the junction. RoHS stands for "Restriction of Hazardous Substances" which states that manufacturers must limit the use of certain hazardous materials such as lead, mercury, cadmium, and others. REACH stands for "Registration, Evaluation, Authorization and restriction of Chemicals" which is a European-wide regulation that requires companies that use certain chemicals to register with the European Union, assess the risks posed by those chemicals, and if necessary, authorize or restrict them. The BZT52C36 Zener Diodes SOD-123 RoHS devices have a thin-film passivated surface and a planar structure for high reliability.
