Semikron SKKT 72/16 E Thyristor Diode Module 70A 1.6kV

Semikron SKKT 72/16 E Thyristor Diode Module provides an average forward current of 70A and a peak repetitive off-state and reverse voltage of 1.6kV, making it suited to controlling high-power circuits. This SEMIPACK 1 Thyristor/Diode Module is designed for demanding power management applications.

Construction

The module uses hard-soldered joints for robust mechanical and electrical integrity, supporting long-term operational stability in harsh environments. Heat dissipation is handled through an aluminium oxide ceramic isolated metal baseplate, which is UL recognised (E63532).

Performance

The on-state RMS current is rated at 125A, allowing the module to handle significant power loads. The gate trigger parameters are specified with a maximum trigger current of 150mA and a maximum gate trigger voltage of 3V, supporting controlled and reliable switching. The maximum operating junction temperature is 125°C.

Applications

The primary uses of the SKKT 72/16 E include the following areas:

• Motor drive control for industrial machinery
• Lighting control systems
• General power management in industrial and commercial equipment
