Metal Diode 40A Cathode Stud Mount

Description

Metal Diode 40A Cathode Stud Mount This heavy-duty Metal Diode 40A Cathode Stud Mount delivers robust performance in high-power environments, supporting continuous currents up to 40 A and reverse blocking voltage of 1200 V. Housed in a durable DO‑5 (DO‑203AB) metal package with a threaded stud cathode, it ensures efficient thermal dissipation when mounted to heatsinks. With a maximum forward voltage drop of approx. 1.3 V and high surge capacity, it is ideal for demanding applications such as industrial power supplies and solar/battery control systems. Features Handles up to 40 A continuous current with excellent surge capability (~570 A, 50 Hz half-wave). Rated for 1200 V repetitive peak reverse voltage, suitable for high-voltage applications. Low forward voltage drop (~1.3 V at surge conditions). Rugged metal DO‑5 package with stud cathode for secure heatsink mounting. Tin-plated metal threading ensures reliable mechanical and electrical contact.
