Product Description

The TD140N18KOF is a high-performance thyristor-diode module from Infineon Technologies, designed for phase control applications requiring robust power handling and reliability. Housed in a compact PB34 package, this module features a 1800 V repetitive peak reverse voltage (V_RRM) and an average forward current rating of 140 A at 85°C. Its dual-component design integrates a thyristor and a diode, providing efficient AC switching capabilities. The module employs pressure contact technology, ensuring high mechanical strength and excellent thermal performance. With a surge on-state current capability of 3200 A and a maximum operating temperature of 125°C, the TD140N18KOF is well-suited for demanding applications such as motor control, industrial heating, welding equipment, and uninterruptible power supplies (UPS).
