17 mm Multi-chip power modules

A particular advantage of the POWERSEM 17 mm bridge rectifiers is that everything has been adopted from the previous 30 mm models with the exception of the height: All new rectifiers with a height of 17 mm have the same electrical and thermal properties as their 30 mm predecessors, which greatly simplifies their use in many applications.

In the three-phase bridge rectifier modules, the PSDS 62 (63 A at 110°C housing temperature) and PSDS 82 (88 A at 110°C) have been joined by the PSDS 63 (75 A at 100°C) and PSDS 83 (100 A at 100°C), which have been available since the end of 2008. Also new are four different single-phase bridge rectifiers with the same dimensions: PSBS 62 (52 A at 100°C), PSBS 63 (60 A at 100°C), PSBS 82 (72 A at 100°C) and PSBS 83 (88 A at 100°C).

More powerful bridge rectifiers in a slightly larger design and 17 mm height are three-phase PSDS 112 (127 A at 90°C), PSDS 162 (175 A at 90°C) and PSDS 192 (248 A at 90°C) as well as single-phase PSBS 112 (84 A at 100°C), PSBS 162 (122 A at 100°C) and PSBS 192 (174 A at 100°C). All new types are available with dielectric strengths from 800 to 1800 V. A higher packing density is possible with the new modules, which is why further 17 mm power modules from POWERSEM are in preparation.
