The SEMIKRON SKKD162/20H4 is a three-phase diode bridge rectifier module rated at 162A average output current and a peak repetitive reverse voltage of 2000V. Engineered for high-reliability AC-to-DC rectification, this module incorporates fast-recovery diodes in an isolated baseplate package optimized for heatsink mounting. Its high blocking voltage rating makes it well-suited for demanding industrial environments where transient overvoltages and line disturbances are common. SEMIKRON's SKKD-series modules are recognized for consistent thermal performance and long service life in continuous-duty power conversion systems.

The SKKD162/20H4 is widely deployed in industrial variable-speed drives, servo amplifiers, uninterruptible power supplies, and crane and hoist motor controls where robust rectification of three-phase mains is required. It is also used in welding equipment, induction heating systems, and large-format battery chargers that demand stable, high-current DC bus generation. Applications in marine drives, mining equipment, and oil and gas power conditioning also rely on this voltage class and current rating. Engineers specifying front-end rectifier stages for harsh-duty or high-availability systems consistently turn to SEMIKRON SKKD modules for their proven thermal cycling endurance.

Key Features of the SKKD162/20H4:

• 162A average rectified output current (ITAV) for high-current industrial rectification stages
• 2000V peak repetitive reverse voltage (VRRM) providing substantial margin against line-side transients
• Three-phase bridge configuration delivering full-wave rectified DC output with low ripple
• Electrically isolated copper baseplate for direct heatsink mounting and simplified thermal management
• Industry-standard SKKD footprint ensuring drop-in compatibility with existing drive and converter platforms
• Optimized forward voltage drop and low thermal resistance (RthJC) supporting high duty-cycle continuous operation

With a factory lead time of up to 99 weeks for new production, the SKKD162/20H4 presents a significant sourcing challenge for maintenance teams managing unplanned downtime or procurement professionals building safety stock. ATI Accurate Technology maintains an active network of verified distributor and excess inventory channels specifically to bridge these gaps. Whether you are replacing a failed module in a critical drive system or planning ahead for a multi-unit installation, our team can locate genuine SEMIKRON stock, verify part markings, and move quickly on your behalf to minimize production risk.
