LED Package/ Die Sizes - WIP -

LED Flashlights – General Info
1

I am looking to put together information about the substrate and actual die sizes of the LED's that we use in our lights.

Any help with this resource would be greatly appreciated and save me some hours of time searching.

So if you know any numbers or have any failed de doming attempts and digital calipers laying around then you can help me put this table together :THUMBS-UP:

Feel free to point out any mistakes or suggestions .

So far we have:

Awesome, this should be stickied, hint hint :wink:

3

Maybe once it’s finished, if people help to fill it out :wink:
This will be part of my LEDs & Other Stuff thread but should also prove useful as a standalone.

4

I suggest adding XB-D. We don’t use it in our flashlights, but many automotive lights use them.

5

Can you change the colors? I seriously can’t read that! Good dataset!

6

Looks good CRX. Maybe include the voltage of the leds as well?

7

Hi all, I found this and seems interesting at least to me, but maybe the experts he can go further.

8

Die size in mm² would be nice.

9

1.5*1.5 LED
0.6*0.75 die
luminous flux 120/110 @350mA
3.3V
5000 and 5700K

10

Nice project!

At least the XP-G die size is not correct yet, it is very close to 1.5 x 1.5 mm.

When I have time I will measure some leds for the table

11

Measured DIE-sizes of many well known LEDs can be found here (it's in German) and in other threads/posts of sma (he is also a member here on BLF). He even subtracts the area of the DIE where the Bond-Wires are.

Here are some interesting ones (all without dome):

Cree XR-E EZ1000: 0.92mm^2

Cree XR-E EZ900: 0.73mm^2

Cree XP-C: 0.44mm^2

Cree XML: 3.9mm^2

Cree XM-L2: 3.94mm^2

Cree MT-G2: 15.7mm^2

Cree XP-E2: 0.85mm^2

Cree XP-G2 (old 1st version 2012-2015): 1.66mm^2

Cree XP-G2 (2nd version, 2015, the ones that luminarium iculator likes so much): 2.18mm^2

Cree XP-L: 4.13mm^2

Cree XP-L HI: 3.67mm^2

Cree XHP-35 HI: 5.9mm^2

Nichia 219B: 2.2mm^2

Also some are easy to find elsewhere.

Luminus SST-50: 2.25mm x 2.25mm = 5mm^2

Luminus SST-90 & SBT-90: 3mm x3mm = 9mm^2

Luminus SBT-70: circular, 7mm^2

Luminus CBT-140: circular, 14mm^2

Some guesses from me:

Cree XHP-70: 4 x XP-L

Luminus CSM-360: 4 x 3mm x 3mm = 36mm^2 (largest power led array?)

12

Didnt know that sst-90 is such that big
I always thought it’s same size of mt-g2

13

The SST-90 ist much smaller than the MT-G2…

14

So XP-L HI and HD have different dies?
Seems to contradict exactly the same voltage characteristic…

15

Always looking for better information…

16

Here are some of the SST-40 properties I could find. Still looking for die size though

Package Size: 4,95 x 4,95 mm
Diagonal Max: 7,00 mm
Total Height: 2,86 mm
Dome Diameter: 2,26 mm
Die size: ???

Source: http://www.luminus.com/products/Luminus_SST40W_Datasheet.pdf

17

The SST-40 datasheet above actually specifies die size. It’s called “LED Emission Area” and it’s 4.0 mm.

18

4mm squared.
The die size is 2mm x 2mm.

19

CRX, could you add SST-40 to the first post?

20

Yeah I’ve been meaning to update this.
