Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Mounted onto a 1500 mm
2
, Denka K1, 1.5 mm AI, 2 kV thermally conductive dielectric, 2 oz. Cu, or equivalent board. Heat sinking should
be spread equally among all pins (caution: pin 2 must be electrically isolated).
2. Mounted onto a 2−layer, 1000 mm
2
per layer, 3 oz Cu, FR4 PCB. Heat sinking should be spread equally among all pins (caution: pin 2 must
be electrically isolated).
3. Mounted onto a 2−layer, 50 mm
2
per layer, 1 oz Cu, FR4 PCB. Heat sinking should be spread equally among all pins (caution: pin 2 must
be electrically isolated).
NOTE: Normally this device would be mounted on the same copper heat sink and adjacent to the LED(s). If the LED(s) were to go open,
then the HBL shunt would now dissipate the power using the same copper heat sink. Since the HBL has a voltage that is lower
than that of the LED(s), then the power dissipation would be easily handled by the same heat sink as the LED.
