SLLIMM high power

The SLLIMM (small low loss intelligent molded module) High Power (HP) series of compact, powerful, dual-in-line intelligent power modules (IPMs) from the STPOWER family expands the existing SLLIMM series in terms of breakdown voltage, current capability, power range, and package options for even greater design flexibility.

New design opportunities and smaller BOM

The new IPMs integrate a complete inverter stage, including six short-circuit rugged IGBTs with freewheeling diodes, associated with high-side and low-side gate drivers in a single package that is designed to optimize thermal dissipation and efficiency.

The modules also contain built-in features for protection and control: bootstrap diodes, undervoltage lockout, shutdown input/fault output, an NTC thermistor for temperature monitoring, and a comparator for fault protection.

SLLIMM HP IPMs allow designers to replace traditional power circuits based on various discrete components or modules with a compact, all-in-one, integrated device that simplifies circuit layout and shrinks the bill of materials. This helps improve the safety, reliability, and cost-effectiveness of the final application.


The SLLIMM HP series is tailored for high-power industrial applications, such as motor drives and inverters operating up to 7 kW at frequencies up to 20 kHz.
