The Semikron SKKE120F17 is a high-power diode module delivering a 120A average forward current rating and 1700V repetitive peak reverse voltage (VRRM). Built on Semikron's proven SKKE platform, this module integrates rectifier-grade diodes in an isolated baseplate package optimized for low thermal resistance and reliable heat dissipation. It is engineered for continuous operation in high-voltage DC bus systems where junction temperature stability and reverse recovery performance are critical parameters. The 1700V class rating provides the necessary voltage headroom for medium-voltage drive and converter topologies common in heavy industrial environments.

The SKKE120F17 sees widespread deployment across industrial AC/DC rectifier front-ends, regenerative drive systems, traction converters, and UPS infrastructure where sustained high-voltage blocking and current-handling capability are non-negotiable. It is equally at home in wind turbine converters, solar string inverters, and industrial welding power supplies. Maintenance engineers specifying replacement modules for legacy variable frequency drives or updating rectifier stages in motor control centers will find the SKKE120F17's electrical profile directly compatible with equivalent 1700V-class diode module sockets in those platforms.

Key Features of the SKKE120F17:

• 1700V repetitive peak reverse voltage (V_RRM) providing robust margin for medium-voltage converter topologies
• 120A average forward current (I_FAV) rating supporting high-power rectifier and freewheeling circuit demands
• Isolated copper baseplate construction enabling direct heatsink mounting without additional electrical isolation hardware
• Low forward voltage drop (V_F) minimizing conduction losses and reducing thermal stress at full load
• Semikron SKiip-compatible footprint and industry-standard SKKE housing for straightforward drop-in replacement in existing designs
• Optimized reverse recovery characteristics (t_rr, Q_rr) reducing switching-induced EMI in high-frequency rectifier stages

With a factory lead time of 37 weeks for new production, the SKKE120F17 represents a significant procurement challenge for facilities requiring unplanned replacements or project builds on compressed timelines. Semikron's 1700V diode module series has historically experienced allocation constraints driven by traction and renewable energy demand surges. ATI Accurate Technology maintains active sourcing channels for long-lead-time and allocated Semikron product lines, giving procurement teams an alternative path to securing genuine OEM inventory without waiting out full factory lead times. Contact ATI early to check current pipeline availability and lock in pricing before lead times extend further.
