175V 50W Stud Mount Zener Diode Reverse Polarity

High Power Voltage Regulation with 175V Nominal Zener Voltage

This 175V 50W zener diode is engineered for demanding voltage regulation and transient suppression tasks. Featuring a nominal regulating (zener) voltage of 175 volts and a robust 50-watt power rating, this stud mount zener diode is ideal for circuits that require stable voltage reference and reliable overvoltage protection.

Reverse Polarity, Stud Mount Construction

Designed with a reverse polarity (cathode to stud) configuration and DO-5 (DO-203AB) stud mount package, this zener diode ensures secure mechanical mounting and optimal thermal dissipationmaking it well-suited for power regulation in industrial and commercial electronics. The stud mount design allows direct attachment to heat sinks or chassis for reliable operation in high-power environments.
