Chapter 7 Cautions
•
This IPM should be used within their absolute maximum rating (voltage, current, temperature, etc.). This IPM may be
broken if used beyond the rating.
•
Don’t design and use the IPM in excess of the absolute maximum ratings (voltage, current and temperature). The IPM
might be damaged if the IPM is used in excess of the absolute maximum ratings.
•
Please refer this Application Manual (MT6M1234) about detailed information for usage, PCB layout, and mounting
instruction.
•
The equipment containing this IPM should have adequate fuses or circuit breakers to prevent the equipment from causing
secondary destruction (ex. fire, explosion etc.).
•
Please confirm the turn-off current and voltage are within the RBSOA.
•
Consider the possible temperature rise not only for the junction and case, but also for the outer leads. Please confirm
these temperatures are within the absolute maximum ratings.
•
The IPM is made of incombustible material. However, if the IPM fails, it may emit smoke or flame. When operating the
IPM near any flammable place or material may cause the IPM to emit smoke or flame in case the IPM become even hotter
during operation. Please take measures to prevent the spread of fire.
•
Do not touch the leads or package of the IPM directly while power is supplied or during operation in order to avoid electric
shock and burns.
•
Connect an appropriate ceramic capacitor between Vcc terminal and gounrd to prevend high frequency noise such as
switching noise.
•
The IPM might be damaged when a noise is applied to the control terminals. Please use the IPM after confining the effect
of noise.
•
The high-side IGBTs are possibly turned on if the VB voltage reduced to less than
V
B(off)
. Please connect appropriate
ceramic capacitors between VB(U) and U terminal, VB(V) and V terminal, VB(W) and W terminal respectively.
•
The input signal voltage should be higher than the threshold voltage.
•
Use this IPM within their reliability and lifetime under certain environments or conditions. This IPM may fail before the
target lifetime of your products if used under certain reliability conditions. If the IPM is used in excess of the reliability, the
IPM might be broken before the system life time.
•
The life time of the semiconductor products is NOT unlimited. Please consider the thermal fatigue caused by temperature
cycle due to self-generated heat. Please use the IPM within the ΔTj power cycle lifetime and ΔTc power cycle lifetime.
The ΔTc power cycle depends on the case temperature (
T
c
) rise and fall, and the Tc is affected by the cooling conditions
of the system. Please consider the heat generation of the IPM and design the cooling condition to achieve target life time.
•
The IPM should not used in an environment in the presence of acid, organic matter, or corrosive gas (hydrogen sulfide,
sulfurous acid gas etc.)
•
The IPM may not used in an irradiated environment since they are not radiation-proof.
•
It is recommended that any handling of the IPM is done on grounded electrically conductive floor and tablemats.
•
Be careful when handling this IPM for ESD damage. (It is an important consideration.)
•
When handling the IPM, hold them by the case (package) and don’t touch the leads and terminals.
•
Before touching the IPM, discharge any static electricity from your body and clothes by grounding out through a high
impedance resistor (about 1MΩ)
•
When soldering, in order to protect the IPM from static electricity, ground the soldering iron or soldering bath through a low
impedance resistor.
•
Don’t apply a mechanical force to deforming the terminals.
•
During open short test, the internal of the IPM might explode instantaneously and the resin mold package might be blown
off when high voltage is applied to the low voltage terminals. Make sure in your design that during open short test, high
voltage will not be applied to the low terminals. To avoid accidents and explosion damage if high voltage is applied, use
fuses in your design.
