（2）Output derating by PCB
When use with different measurement conditions from
output derating by ambient temperature, use output
derating by PCB temperature as in Fig.1-13 and
1-14. PCB temperature is decided by temperature
of thermal sensor in below Fig.1-12. As the ther-
mal sensor terminals are exposed, when connecting
thermocouple, please take sufficient insulation from
terminals. Over Thermal Protection of power module
is achieved by detecting the PCB temperature through
thermal sensor. When the module operates over the
output derating curve of PCB temperature, Over Ther-
mal Protection (OTP) functions and output shutdown.
Therefore, measurement of PCB temperature is rec-
ommended to ensure the module to operate within the
derating curve.

2 Mounting Method
（1）Prohibition area of pattern wiring
Avoid wiring pattern on PCB in shaded area as
shown in Figure 2-1 as it may cause insulation prob-
lem.
Since the power module may influence by noise, care
must be taken when wire the signal line on the un-
shaded area.
