Page 8: Dimensions And Mechanical Precautions
The primary side and the two secondary side plug-in connectors are 10 pin dual row 2.54mm pin headers. For a secure mechanical connection of the SKYPER 12 PV IGBT driver it is essential that the pin headers can be fully supported by the female mating connectors. -
Page 9: Support Post
Support post To increase the robustness of the mechanical connection between the SKYPER ® 12 PV driver and the corresponding board a support post could be assembled. If a support post is used, make sure it has the correct length. A too short support post would bend both, the driver and the corresponding board that it is mounted on, thus increasing mechanical stress. -
Page 10: Handling Instructions
When handling the driver, do not pick up the driver at the transformers. The driver MUST be handled at the PCB sides.

Page 17: Error Mode Selection | Primary Side
Error mode selection | Primary side The configuration pin CFG_ERR selects the behavior of the SKYPER ® 12 PV driver core on error events. Connecting the CFG_ERR pin to the PWR_GND pin forces the driver to set its outputs to off-state immediately when an error is detected. - Page 18 CFG(temp) thermistor and the desired trip level.

Page 26: Dynamic Short Circuit Protection By
SEMIKRON recommends to set the DSCP trip level to a value of 7V to 9V (voltage at the CFG_VCE pin) to prevent from unwanted accidently (false) triggered desaturation events due to a too small gap between the saturation voltage of the IGBT and the trigger level of the DSCP feature. -
