XLN-RECT100A
Xinleineng XLN-RECT100A 1600V 100A high-power ultrafast rectifier for 50-100kW applications.
Product Overview
Description
The Xinleineng XLN-RECT100A is a 1600V 100A three-phase bridge rectifier module with ultrafast recovery diodes. This high-power module is designed for motor drives from 50kW to 100kW, large UPS systems, and solar inverter input stages. The ultrafast recovery characteristic (<200ns) ensures low switching losses in high-frequency applications while soft recovery minimizes EMI. The 100A continuous current rating supports the high DC currents in megawatt-scale power conversion. The module features integrated NTC temperature sensing and is packaged in the standard 62mm form factor.

FAE Expert Insights
"The XLN-RECT100A handles high-power applications with ease. I have deployed this in 75kW solar inverter designs where the DC input current can exceed 100A. The 62mm package provides good thermal performance - with liquid cooling or large heatsinks, the module maintains safe operating temperatures. The ultrafast recovery is critical for high-frequency inverter designs to minimize input stage losses. One important consideration: DC bus capacitance must be sized appropriately for the high ripple current. I recommend film capacitors with at least 50A ripple current rating per module."

Frequently Asked Questions
What is the recommended heatsink thermal resistance for XLN-RECT100A?
XLN-RECT100A at 100A continuous current generates approximately 100W conduction loss (1.0V x 100A). For junction temperature below 125C with 40C ambient, required total thermal resistance is (125-40)/100 = 0.85C/W. With RthJC of 0.3C/W and RthCS of 0.1C/W (thermal grease), the heatsink should have RthSA of approximately 0.45C/W. This typically requires a forced-air heatsink with 500+ LFM airflow or a liquid-cooled cold plate. Natural convection heatsinks are generally insufficient for continuous 100A operation.
Contact FAE for detailed thermal design calculations for your specific cooling method.
How do I parallel XLN-RECT100A modules for higher current?
Paralleling rectifier modules for currents above 100A requires careful design: Use matched modules from the same production batch for consistent forward voltage characteristics; Mount all modules on a common heatsink for thermal coupling - this provides negative feedback for current sharing; Use symmetrical busbar layout with equal impedance to each module; Add small resistance (0.1-0.5 mohm) in each module lead if current imbalance is observed; Monitor individual module temperatures to verify balanced operation. For very high currents (200A+), consider custom busbar designs with proper thermal management.
Contact FAE for parallel rectifier design assistance including busbar layout recommendations.
What protection is recommended for rectifier modules?
Rectifier protection includes: TVS diodes or varistors on AC input to clamp voltage transients; DC bus overvoltage protection through voltage sensing and crowbar or chopper circuits; Thermal protection using NTC thermistor to shutdown if temperature exceeds limits; DC bus fuses or circuit breakers coordinated with downstream protection; EMI filtering on AC input to meet conducted emission limits. For motor drive applications, include protection against regenerative overvoltage when the motor acts as generator.
Implement comprehensive protection including voltage clamping and thermal monitoring.
What is the typical efficiency when using XLN-RECT100A?
The XLN-RECT100A achieves high efficiency through optimized design. Conduction losses are minimized with low forward voltage drop, and switching losses are controlled through proper gate drive design. Overall system efficiency depends on operating conditions, switching frequency, and thermal management. Contact FAE for efficiency calculations specific to your application.
Optimize efficiency by selecting appropriate switching frequency and implementing proper thermal design.
What are the common failure modes of XLN-RECT100A and how to prevent them?
Common failure modes include thermal overload from insufficient cooling, overvoltage from switching transients, and mechanical stress from thermal cycling. Prevention measures include proper heatsink sizing, voltage clamping with TVS diodes, and following recommended mounting procedures. The integrated protection features help prevent damage from abnormal operating conditions.
Implement comprehensive protection and follow recommended operating conditions to ensure reliable operation.
