ZP30A (or ZP-30A) Stud Mount Rectifier Diode

The ZP30A is an industrial grade silicon power diode designed for high current rectification. It features a rugged stud mount design that allows the device to be bolted directly to a metal heat sink or chassis. This mechanical configuration is necessary to dissipate the heat generated while conducting 30 Amperes of current. These diodes are common in battery chargers, welding equipment, and large DC power supplies. They are valued for their high surge current capacity, which helps the circuit survive temporary overloads or startup spikes. The device is usually available in two configurations: stud cathode, where the threaded bolt is the cathode, and stud anode, where the bolt is the anode. This flexibility allows users to build bridge rectifiers or other power configurations with minimal wiring.

Key Features:

Repetitive peak reverse voltage ranging from 100 to 1600 Volts depending on the specific model.

Maximum forward voltage drop of 1.6 Volts.

Peak forward surge current of approximately 470 Amperes.

Operating temperature range from minus 40 to plus 150 degrees Celsius.

Standard M6 or M8 threaded stud for heat sink mounting.
