Conclusion

Several tests performed on the new advanced planar PT STGW35HF60WD show that

STMicroelectronics’ advanced PT technology can be paralleled with satisfactory

performance in terms of thermal and current sharing. Reliable paralleling, however, requires

good thermal feedback implementation and VCE(sat) selection of the total IGBT population.

Both of these factors provide a balancing mechanism to reduce and keep stable the

dynamic

∆IC at operating conditions. Finally, the STGW35HF60WD is offered in three

different VCE(sat) groups, as shown in Table 2: Suggested VCE(sat) (@20 A, 25 °C, 15 V)

selection as per datasheet and as reported in the datasheet, for a safe parallel connection

without risk of thermal runaway.

The VCE(sat) grouping reported above is slightly different from the one in Figure 6, in order to meet the

testing rules.
