Note1. Represent ratings and characteristics of the anti-parallel, emitter-collector free wheeling diode (DIODE).
2. Junction temperature (T
j
) should not increase beyond T
jmax
rating.
3. Pulse width and repetition rate should be such that the device junction temperature (T
j
) dose not exceed T
jmax
rating.
4. Case temperature (T
C
) and heat sink temperature (T
s
) are defined on the each surface (mounting side) of base plate and heat sink
just under the chips. Refer to the figure of chip location.
5. Pulse width and repetition rate should be such as to cause negligible temperature rise.

7. Typical value is measured by using thermally conductive grease of λ=0.9 W/(m·K).
8. The base plate (mounting side) flatness measurement points (X, Y) are as follows of the following figure.
9. Use the following screws when mounting the printed circuit board (PCB) on the stand offs.
"φ2.6×10 or φ2.6×12 self tapping screw"
The length of the screw depends on the thickness (t1.6~t2.0) of the PCB.
