The DSAI75-16B-IXYS is a high-voltage avalanche rectifier diode module rated at 75 amperes and 1600 volts, manufactured to IXYS standards for robust performance in demanding power conversion applications. The avalanche-rated junction construction provides controlled breakdown characteristics, giving the module inherent protection against repetitive transient overvoltages that would otherwise stress or destroy conventional rectifier diodes. Its standard power module package simplifies heatsink mounting and bus-bar integration, making it a reliable drop-in solution for new designs and field replacements alike.

This module is well suited for industrial AC-to-DC rectification stages, freewheeling diode positions in motor drive front ends, UPS and battery charger topologies, induction heating power supplies, and resistance welding converters. Wherever a 1600V blocking voltage and 75A average forward current are required alongside avalanche ruggedness, the DSAI75-16B-IXYS delivers the thermal and electrical margin needed for continuous duty cycles. It is equally applicable in traction auxiliary supplies and renewable energy inverter DC links where transient immunity is critical.

Key Features of the DSAI75-16B-IXYS:

• 1600V repetitive peak reverse voltage (VRRM) for high-voltage DC bus and line rectification circuits
• 75A average forward current rating suitable for medium-power industrial converter stages
• Avalanche-rated junction technology provides controlled, repetitive avalanche capability protecting against voltage transients without external clamping in many topologies
• Low forward voltage drop minimizes conduction losses and reduces heatsink thermal requirements
• Isolated baseplate construction allows direct heatsink mounting without additional insulating hardware, simplifying mechanical assembly
• Industry-standard power module footprint ensures dimensional compatibility with IXYS and cross-manufacturer heatsink systems for straightforward field replacement

The DSAI75-16B-IXYS reflects the broader IXYS high-voltage diode module family, a product line that has seen extended lead times and diminishing distributor inventory as the industry shifts procurement cycles. Procurement teams managing aging drive platforms, legacy UPS infrastructure, or installed welding equipment often encounter this module as a critical long-lead or discontinued item. ATI Accurate Technology actively sources and maintains stock of exactly these hard-to-find components, enabling maintenance teams to execute unplanned repairs without extended downtime waiting on factory lead times that can stretch to 26 weeks or beyond.
