SKD53/16
The SKD53/16 from Semikron is a high-performance three-phase power bridge rectifier designed to meet the rigorous demands of modern power electronic systems. With a repetitive peak reverse voltage (V_RRM) of 1600 V and a direct output current (I_D) of 53 A at 100°C, it ensures efficient and reliable DC conversion in various industrial applications. Its robust construction features glass-passivated silicon chips and a direct copper bonded aluminum substrate (DCB) base plate, resulting in low thermal impedance and enhanced durability. This design choice contributes to the module's ability to handle high surge currents up to 270 A, making it suitable for environments with high vibrations and thermal stresses.
The SKD53/16 excels in applications requiring stable and efficient power conversion. It is ideal for three-phase rectifiers in power supplies, input rectifiers for variable frequency drives, rectifiers for DC motor field supplies, and battery charger rectifiers. Its compact dimensions (63.5 x 29.5 x 17 mm) and G55 housing type facilitate easy integration into existing systems, whether through PCB mounting or wave soldering. The module's ability to operate at a junction temperature of up to 150°C and its low on-state voltage of 1.5 V further enhance its efficiency and reliability in demanding industrial and commercial environments.
In summary, the SKD53/16 power bridge rectifier offers a combination of high voltage capability, substantial current handling, and thermal robustness, making it a preferred choice for professionals seeking reliable performance in power electronic applications. Its design ensures longevity and efficiency, catering to both industrial and commercial needs. For more detailed information, please refer to the Semikron datasheet: semikron-danfoss.com.
