New 800V TRIACs from Renesas with high
commutation characteristics
Renesas has developed new 800V TRIAC products, including
the BCR16CM-16LH, with high commutation characteristics
with a guaranteed junction temperature (Tj) of 150 Deg C,
making them ideal for AC motor drive applications in electric
household appliances such as washing machines and vacuum
cleaners.
The main features of the new TRIAC products are as follows.
1. Higher commutation to reduce the total number of components
The new TRIACs have a voltage rating of 800 V and achieve
the highest commutation level. The critical rate of rise
of off-state commutating voltage (dv/dt)c, for which a high
value is desirable to avoid malfunction, is approximately
two to 20 times that of previous Renesas Technology TRIAC
products. This ensures that the TRIAC can turn off surely
when controlling an inductive load such as a motor and eliminates
the need for a CR absorber circuit to prevent malfunction
during commutation, thereby reducing the overall system
cost
.
2. Guaranteed voltage of 800 V and junction temperature
(Tj) of 150 Deg C
The new TRIACs have a guaranteed voltage of 800 V to ensure
safe operation in regions where the power supply voltage
is AC 200 V, such as Europe and Asian countries including
China, South Korea, and India. Renesas Technology has previously
released a series of 700V TRIACs with a guaranteed junction
temperature (Tj) of 150 Deg C. The new TRIACs achieve a
junction temperature (Tj) of 150 Deg C and 800 V. This makes
thermal design much easier when compared with 125 Deg C
TRIAC products and allows the use of a smaller cooling fin.
The new TRIACs use a planar technology and minimize off-state
leak current.
To match a variety of electric household appliances (white
goods), the lineup of new TRIACs are the current ratings
of 4 A, 10 A, 12 A, and 16 A, and the available packages
are uninsulated TO-220 and MP3A and insulated TO-220FL.
