This document describes the features and applications of Dynex Semiconductor's DCR3640W series double side cooled, high surge capability phase control thyristors.
The DCR3640W52 is a double‑side‑cooled phase‑control thyristor designed for high‑surge capability, high voltage power supplies, and static switches. It offers a peak voltage rating of 5200 V, continuous on‑state current up to 3550 A, and surge current capability of 49 kA (10 ms half‑sine). Applications include high‑power drives and high‑voltage power supplies.
Ordering information, package dimensions, and thermal management options are detailed, with a W‑type outline and lead length of 420 mm. Dynex provides a range of air and liquid‑cooled heatsink assemblies and clamping systems to support the device’s performance.
