SLLIMM nano series packages

The STPOWER SLLIMM nano IPM product family, including SLLIMM nano SMD, SLLIMM nano through hole, and SLLIMM nano 2nd series (all with through-hole packages), offers products with different switching options (IGBTs or high voltage MOSFETs) and 3 half-bridge control ICs for gate driving. The devices feature a current capability from 1 to 8 A and a breakdown voltage of 500 and 600 V.

Different full-molded packages are available, both through-hole (in zig-zag and dual in-line lead options) and SMD versions.

These compact, thermally efficient IPMs can be tailored for home appliances such as roller shutters, fridges, dishwashers, and low-power washing machines as well as pumps, fans, and motor drives working up to 600 W and 20 kHz in hard-switching circuitries.

The SLLIMM nano family offers products with a high integration level that fully satisfy space-saving needs without any compromise on the thermal performance and reliability standards required for low-power inverter applications.

These products, regardless of the package type, share the same internal topology, based on six switches and three half-bridge IC gate drivers, including additional features and protections.

Furthermore, the different lead finish types (in-line and zig-zag packages) offer additional flexibility for meeting customer needs.


IPMs offer the best compromise between conduction and switching energy with an outstanding robustness and EMI behavior, making the products ideal to enhance efficiency in low-power motors working up to 20 kHz in hard-switching circuitries:

Dish machine
  • Dishwashers
  • Dryers
  • Kitchen hoods
  • Refrigerators and freezers
  • Washing machines
  • Fans
  • Fans
  • Pumps and compressors
Industrial motor control
  • PMSM / BLDC motor control
  • Induction motor control

Product types

The SLLIMM nano IPMs are available in different full-molded packages: surface mounting (SMD) and through-hole (TH) options.

This dual in-line compact and thermally efficient package enhances reliability and allows heatsink-free design, while the increased creepage and clearance between the leads assure safety isolation at body package level. The SMD package is ideal for all the application boards where the reflow and wave soldering processes are mandatory, targeting low-power applications such as roller shutters, small fans, small compressors, and any motor driver up to 80 W.
SLLIMM nano through hole
This compact IPM in a through-hole package (zig-zag and dual in-line options), suitable for motor control applications up to 110 W, is the ideal solution for reducing the assembly PCB/system space without sacrificing thermal performance and reliability.

SLLIMM nano 2nd series

This IPM ensures easier heatsink fastening with the use of dedicated slots implemented on the package body, thus it helps improve the device’s thermal performance. The series is UL 1557 recognized (file E81734) up to 2 kVrms/60sec. The series offers a double-lead option: in-line and zig-zag, with and without stand-off options, and is tailored for motor drive applications for a range up to 600 W.
