The Semikron SKKD46/12 is a robust rectifier diode module designed for industrial power distribution. It features a dual-diode configuration within the SEMIPACK 1 housing, offering a repetitive peak reverse voltage of 1200V and a mean forward current of 46A at 85°C.
This module is built for high-duty cycles, employing pressure contact technology to eliminate solder fatigue and extend service life under cyclic loads. The isolated metal baseplate with aluminum oxide ceramic ensures consistent thermal performance and high insulation voltage, making it suitable for line rectifiers and DC power supplies.
With a surge current rating of 700A, the SKKD46/12 is engineered for reliability in harsh industrial environments. Its high surge capacity acts as a safety buffer, preventing diode failure during motor startup in applications like Variable Frequency Drives (VFD) and Servo Drives.
The junction-to-case thermal resistance is 0.85 K/W per diode, contributing to its high thermal margin. The module is designed for 400V and 440V AC line applications, prioritizing thermal headroom and mechanical durability.
