The MCMA700PD1600CB-IXYS is a 700A, 1600V chopper-configuration IGBT power module manufactured to IXYS CB-series platform specifications. Decoding the part number: MCMA indicates a modular chopper topology with a single IGBT switch and antiparallel freewheeling diode; 700P denotes 700A collector current; D1600 specifies 1600V blocking voltage; CB identifies the industry-standard CB package footprint. This module is engineered for low saturation voltage and fast, controlled switching transitions, making it well-suited to high-energy industrial power conversion circuits where thermal management and reliability are critical.

This 700A/1600V chopper module sees widespread deployment in DC bus braking choppers for AC and DC variable-speed drives, regenerative energy systems, crane and hoist drive systems, traction inverters, UPS bypass stages, and pulse-width-modulated power supplies. Its high current rating and rugged 1600V blocking capability make it particularly valuable in heavy industrial environments — steel mills, mining equipment, marine drives, and rail traction systems — where load transients are severe and module replacement downtime must be minimized. The CB footprint ensures drop-in compatibility with a broad range of existing drive platform designs.

Key Features of the MCMA700PD1600CB-IXYS:

• 700A continuous collector current with high peak current capability for transient-heavy load profiles
• 1600V VCES blocking voltage providing substantial margin in 690V and 1000V DC bus applications
• Single chopper (half-bridge leg) topology with integrated antiparallel freewheeling diode for simplified braking circuit design
• CB-series industry-standard package footprint enabling direct drop-in replacement in existing IXYS and compatible drive platforms
• Low VCE(sat) characteristics reduce conduction losses and thermal stress at high duty cycles
• Optimized gate drive threshold and transconductance for reliable switching in PWM braking chopper and DC-DC converter topologies

The MCMA700PD1600CB-IXYS represents precisely the class of high-current IGBT module that has become difficult to source through standard distribution channels. IXYS CB-series modules at this current and voltage level frequently carry extended lead times of 26–52 weeks from franchised distributors, and many drive OEMs have discontinued active procurement support. For maintenance engineers managing aging drive fleets or procurement teams facing EOL notification on installed base equipment, securing verified stock from a specialist distributor is often the only path to avoiding extended system downtime.
