Warning:
This manual contains the product specifications, characteristics, data, materials, and structures as of October 2021.
The contents are subject to change without notice for specification changes or other reasons. When using a product listed in this manual, be sure to obtain the latest specifications.
All applications described in this manual exemplify the use of Fuji’s products for your reference only.

Cautions
(1) During transportation and storage
Keep locating the shipping carton boxes to suitable side up. Otherwise,
unexpected stress might affect to the boxes. For example, bend the terminal
pins, deform the inner resin case, and so on.
When you throw or drop the product, it gives the product damage.
If the product is wet with water, that it may be broken or malfunctions,
please subjected to sufficient measures to rain or condensation.
Temperature and humidity of an environment during transportation are described
in the specification sheet. There conditions shall be kept under the
specification.
(2)Assembly environment
Since this power module device is very weak against electro static discharge, the ESD countermeasure in the assembly environment shall be suitable within the specification described in specification sheet. Especially, when the conducting pad is removed from control pins, the product is most likely to get electrical damage.
(3)Operating environment
If the product had been used in the environment with acid, organic matter, and corrosive gas (hydrogen sulfide, sulfurous acid gas), the product’s performance and appearance can not be ensured easily.
1. Troubleshooting
An IPM has various integrated protection functions (such as over current
protection and over heating protection) unlike a standard IGBT module, it
shuts down safely in the case of abnormal conditions. However, it may be
destroyed depending on the abnormality of the failure that occurred. When the
IPM has failed, it is necessary to take countermeasures upon clarification of
the situation and find the root cause of the breakdown.
Failure tree analysis charts are shown in Figure 7-1. Carry out the
investigation of the failure mode by using these charts. For the failure
criteria, see Chapter 4, Section 2 [IGBT test procedures] of the IGBT Module
Application Manual (RH984).
Furthermore, when an alarm signal output is generated from the IPM, investigation of the root cause by referring to the alarm factor analysis chart in Section 3 of this chapter can be done.

(d) Mode D: FWD breakdown Fig.7-1 IPM failure tree analysis chart
(e) Mode E: Control circuit breakdown

(f) Mode F: Breakdown related to reliability and product handling

3. Alarm factor tree analysis chart
When the system equipped with the IPM has stopped and an alarm signal is generated, first carry out investigations to identify whether the alarm signal was generated from the IPM or the device control circuit (other than the IPM).
If the alarm signal was generated from the IPM, identify the factor in accordance with the alarm factor analysis tree chart indicated in Figure 7-2.
Similar to V-IPM, it is possible to identify which protection function is activated by checking the alarm signal pulse width in X-IPM too. Therefore, the factor analysis time can be shorten.
In addition, the alarm signal output voltage can be easily measured by connecting a 1.3 KΩ resistor in series between the IPM alarm signal output terminal and the cathode terminal of the optocoupler.
