ProTek offering unpackaged die for LEDs

October 23, 2012 – ProTek Devices says it is now offering individual unpackaged die for LEDs in wafer form, available as unidirectional and bidirectional electrostatic discharge (ESD) protection diodes.

The new LED die (<6 mils thickness) supports LED lighting voltage at 5V, with other voltages "to be introduced soon," ProTek noted in a statement. The bidirectional die (PLED508 and PLED511) and unidirectional (PLED508U and PLED511U) die have Ti/Ni/Ag back metal and Al/Cu top metal.

The PLED511 LED die has 200,000 diodes/wafer, while the PLED511U has 150,000 diodes/wafer; the PLED508 has 300,000 and the PLED508U has 340,000. All are available as probed good die in wafer form, delivered quartered, sawn, and mounted on blue tape.

In addition to LED lighting manufacturers, other applications for the wafers include digital display boards; automotive LEDs; backlight LEDs, and solid-state lighting. Minimum order quantities are the equivalent of five whole wafers (quartered).
