The BZX85C150 is a 1.3-watt Zener diode from EIC discrete Semiconductors, designed to provide voltage regulation and overvoltage protection in a variety of electronic circuits. It maintains a relatively constant voltage of 150 volts (Vz) across its terminals when the reverse voltage exceeds the Zener voltage. The BZX85 series is known for its robust construction and reliable performance, making it a common choice for power supply regulation and transient voltage suppression.

Additional Details

The BZX85C150 is packaged in a DO-41 (or similar axial-lead) package. Important parameters include the Zener test current (Izt), which is the current at which the Zener voltage is specified, and the reverse leakage current (Ir), which is the current that flows when the diode is reverse biased below the Zener voltage. The thermal resistance should also be considered when designing for high power applications. Ensure proper heat sinking if operating at or near the maximum power dissipation rating. Always consult the manufacturer's datasheet for detailed specifications and application notes. As this part is listed as END-OF-LIFE, consider carefully if its use is appropriate for new designs.
