Acrich2 – 8.7W
Integrated AC LED Solution
Acrich2 – 8.7W Candle
SMJC-XV08W2P4
RoHS
Product Brief
Description
The Acrich2 series of products are designed
to be driven directly off the AC line voltage
(with an SPC board) and do not need the
typical AC/DC converters essential for
conventional lighting products.
The converter or the driver found in most
general lighting products can limit the overall
life of the product, but with the Acrich2 series
the lifetime of the product is based on the
lifetime of the LED itself.
The Acrich2 series also allows for maximum
design flexibility to create a compact and
aesthetic luminaire.
The modules also have a high power factor
which can contribute to additional energy
savings in the end application.

(3) Correlated Color Temperature is derived from the CIE 1931 Chromaticity diagram.
(4) Operating Voltage doesn't indicate the maximum voltage which customers use but means
tolerable voltage according to each country’s voltage variation rate. It is recommended that the
solder pad temperature should be below 70℃.

The Acrich2 LED has a thermal resistance of 23℃/W from junction of the LED to the
LED lead.
The maximum junction temperature of the Acrich2 LED package is 125℃, therefore the maximum
lead temperature T
s_max
is
T
s_max
= T
j_max
- (Rθ

* P

)
= 125℃ - (23℃/W * 1.55W) = 89.35℃
Although this is the maximum lead temperature, it is recommended to keep the lead temperature
under 70℃.
The Acrich2 IC has a 11.25℃/W thermal resistance from junction to the top surface.
The maximum junction temperature (T
j_max
) of the IC is 150℃, therefore the maximum
temperature of the top of the IC is
T

= T

– (Rθ

= 150℃ - (11.25℃/W * 1.0W) = 138.75℃
