SLLIMM 2nd series

The SLLIMM 2nd series is ST’s family of compact and efficient dual-in-line intelligent power modules, with optional extra features.

Based on a 3-phase inverter equipped with IGBTs or superjunction (SJ) MOSFETs, the devices feature a current capability from 8 to 35 A and a breakdown voltage of 600 V. Thanks to the full-molded and top-side cooling direct bonded copper (DBC) package options, these IPMs address low-to-medium to high-power applications.

The SLLIMM 2nd series ensures high efficiency in home appliances such as washing machines, pumps, fans, and air conditioning units as well as motor drives working at up to 20 kHz in hard-switching circuitries from 300 W to 3 kW.

The SLLIMM 2nd series offers higher performance, wider current range and additional package technology options that can further reduce the cost of the application by enabling the use of smaller heatsinks.

The series combines two drivers (one high-side and one low-side) and a power section based on improved trench gate field-stop IGBTs plus freewheeling diodes or N-channel superjunction MOSFETs with fast-recovery body diode. The combination increases efficiency and minimizes EMI and overall losses, ensuring higher short-circuit withstand times.

A built-in temperature sensor and/or an NTC (Negative temperature coefficient) option are available.

Applications:

The SLLIMM 2nd series IPMs show the best compromise between conduction and switching energy with outstanding robustness and EMI behavior, making the products ideal to enhance efficiency in low- and medium-power motors working up to 20 kHz in hard-switching circuitries.

Product types:

The SLLIMM 2nd series features a breakdown voltage of 600 V and a current rating from 8 to 35 A at 25°C.

To maximize the efficiency in steady-state operation and in applications working at low load including high-end air conditioning units, the SJ-MOSFET version is the preferred choice thanks to it very low RDS(on) up to 100 mΩ and lower thermal resistance.

As package options, the full molded option represents a cost-effective solution for medium-power platforms, while the DBC option ensures higher power dissipation thanks to the lowest RTH value.
