As the industrial electronics industry advances, the demand for reliable and high-performance rectifier diode modules becomes increasingly urgent. For purchasing managers and electronics engineers, choosing the right diode module for applications such as AC converters, DC motor supplies, and power rectification is crucial. This article provides a technical comparison and in-depth evaluation of two prominent diode modules—SKKD380/18 from Semikron and PD100KN16 from Kyocera. We’ll explore their core technical parameters, design characteristics, and optimal application scenarios, helping you make informed procurement decisions.
An accurate understanding of product specifications is vital when selecting rectifier modules. Here’s a comparison of the main metrics:
| Parameter | SKKD380/18 | PD100KN16 |
|---|---|---|
| Peak Reverse Voltage (VRRM) | 1800V | 1600V |
| Continuous Forward Current (IF) | 380A | 100A |
| Pulse/Repetitive Current | 600A | — |
| Forward Voltage (VF) | — | 1.54V |
| Operating Temperature Range | -40°C to +130°C (storage) | -40°C to +150°C |
| Mounting | Screw, M5 torque 5±15% | Screw Mount |
| Module Weight | Typical 600g | — |
The SKKD380/18 stands out for its outstanding current handling capability. With a continuous collector current of 380A (and pulse up to 600A), it is ideal for industrial high-power applications. This module features advanced thermal management, using a baseplate isolated via aluminum nitride ceramic—ensuring rapid heat dissipation and high reliability, which is critical for stability in demanding application environments.
Key strengths:
Typical application scenarios include uncontrolled rectifiers for AC converters, rectifiers in transistorized AC motor controllers, and field supplies for DC motors. For further insights into similar high-current diode modules, explore the SKD145-16 product page.
On the other hand, the PD100KN16 offers a forward current capacity of 100A and reverse voltage handling up to 1.6kV. Its low forward voltage drop (1.54V) helps in reducing conduction losses, making it ideal for applications sensitive to efficiency and thermal management—such as precision power supplies or renewable energy inverters.
Advantages include:
The PD100KN16, with its strong brand support (Kyocera electronic components), is well-suited for mid-range power conversion, phase leg diode applications, and custom discrete semiconductor assemblies. Detailed specifications can be found on the PD100KN16 product page.
When considering integration into your system, SKKD380/18 emerges as the prime solution for scenarios where high current load and robust durability are critical, such as industrial motor drives, traction systems, and heavy-duty rectification.
Meanwhile, the PD100KN16 is optimized for situations demanding moderate current handling but high efficiency, compact size, and operational flexibility—making it an excellent fit for distributed power modules, industrial automation circuits, and renewable energy converters.

Both modules utilize screw mounting designs, simplifying on-site replacement and enabling secure installation in industrial settings. The enhanced ceramic insulation of the SKKD380/18 ensures superior protection against electrical breakdowns. In contrast, the PD100KN16, with its RoHS compliance and silicon technology, meets the requirements of high-reliability electronics manufacturing.
Engineers are encouraged to evaluate junction temperature limits, required isolation voltages, and installation constraints to optimize reliability and service life. Proper thermal management and adherence to recommended mounting torque (for example, SKKD380/18’s 5±15% N·m) are vital for maximizing operational stability.
In summary, the SKKD380/18 is the module of choice where very high current capacity, robust isolation, and dependable heat management are key criteria. The PD100KN16 is a compelling option for applications prioritizing energy efficiency, medium current levels, and flexible integration. Both products represent advanced solutions in discrete semiconductor design, meeting the dynamic requirements of modern industrial systems.
