MS1250D225N
The MS1250D225N is a compact, high-reliability snubber module designed to protect and smooth switching transients in IGBT-based power electronics. Engineered for harsh industrial environments, it combines low-voltage-drop, fast reverse-recovery diodes with a metalized polypropylene film capacitor to deliver low loss and fast energy dissipation at high voltages. Rated for 1200 V blocking and designed for heavy switching duty, the module reduces switching overshoot and ringing—improving system efficiency and extending the lifetime of inverter and drive power stages.
Built for durability and easy integration, the MS1250D225N features short internal connections to minimise stray inductance and a compact footprint that helps reduce overall equipment size and weight. Typical applications include IGBT snubber circuits in three-phase inverters, motor drives, UPS systems, and stabilized power supplies where reliable energy absorption and low EMI are critical. Its RoHS-compliant construction and proven components make it suitable for both industrial and commercial installations that demand long-term, low-maintenance operation.
When you need a tried-and-tested snubber solution to tame switching transients and improve converters’ lifetime and performance, the MS1250D225N delivers efficient energy handling, low loss operation, and mechanical robustness in a small package.
