Pin Layout Difference and Equivalent IPM for STGIB8CH60TS-E

We are currently evaluating two ST IPM modules for our motor drive applications — STGIB8CH60TS-E and STGIB15CH60TS-L. Upon reviewing both datasheets, we noticed that although the two devices share the same functional pin descriptions where (STGIB8CH60TS-E have max current of 12A @ 25°C) and (STGIB15CH60TS-L  have a max current of 20A @ 25°C) but package types are different, the physical layout of certain pins, specifically Pin 19 (NV), differs between the two modules.

We would appreciate your clarification on the following points:

  1. What is the technical reason for the difference in Pin 19 layout between the STGIB8CH60TS-E (Type E package) and STGIB15CH60TS-L (Type L package)?

  2. Are there layout-compatible alternatives to STGIB8CH60TS-E (i.e., IPMs with similar electrical characteristics and identical physical pin positions) that could support higher current or allow for flexible sourcing?

Welcome @VishnuNatarajan, to the community!

  1. The extended pin 19 was probably introduced at the time at customer's request.

  2. The STGIB8CH60TS-E is the only remaining variant with this layout in the portfolio of STMicroelectronics.

Does it answer your questions?
