SEMIKRON SKKT 250/16E Thyristor Module 1.6KV 250A

From the shop's description

SEMIKRON SKKT 250/16E Thyristor Module 1.6KV 250A The SEMIKRON SKKT 250/16E is a dual-thyristor power module housed in the industry‑standard SEMIPACK 3 package, designed to deliver robust, reliable performance in demanding power‑electronics applications. Internally configured as two series‑connected thyristors, it enables full phase control and rectification in a compact, low‑inductance housing, with all main terminals on the top for straightforward buss‑bar connections and gate leads clearly marked for ease of wiring. The ceramic base plate ensures excellent thermal conductivity to the heatsink, while the molybdenum‑copper substrate minimizes thermal stress during high‑power operation. Hard‑soldered joints and rugged internal connections confer high mechanical stability and long lifetime under cyclical thermal loading. Rated for up to 250 A mean on‑state current at a case temperature of 85 °C and a repetitive peak off‑state voltage of 1 600 V, the SKKT 250/16E maintains safe operation with a dv/dt class “E” (1 000 V/µs) rating. Its optimized gate characteristics deliver consistent triggering with minimal gate current, simplifying driver design. The compact 115 × 50 × 52 mm footprint and integrated mounting screw locations support straightforward installation in both new designs and legacy equipment. With its blend of high current capacity, voltage blocking, and thermal robustness, the SKKT 250/16E is an ideal building block for high‑power rectifiers, inverters, and soft‑starter modules in industrial and energy‑conversion systems. Features: Dual‐thyristor (thyristor‐thyristor) topology for full‐wave phase control. SEMIPACK 3 ceramic housing with top‐side main terminals for easy integration. Hard‐soldered internal joints ensure high mechanical stability and thermal cycling capability. Low thermal resistance junction‑to‑case for efficient heat dissipation. dv/dt class “E” (1 000 V/µs) rating for robust turn‑off performance. Standard mounting torque and footprint for drop‑in replacement in SEMIPACK 3 systems.
