Mid-power UV LED for disinfection and sterilisation

Called VLMU35CM00-280-120, it comes in a 3.5 x 3.5 x 1.2mm surface-ceramic mount package with a quartz window.

Because of this construction, the firm is claiming “extremely long lifetime” – however, nowhere in the data sheet nor the product page can I find any reference to life data, only a repetition of the ‘long life’ claim – so caveat emptor. Electronics Weekly has requested clarification.

Radiant power is typically 12mW (8mW min) at 100mA (Max is 150mA.

Output is typically 278nm (265-285nm) and forward drop is 4-7V (5Vtyp)

“Designed to replace mercury UVC lamps, the device offers an emission angle of ±60° without the need for an external lens,” said the firm.

It is compatible with re-flow soldering and has moisture sensitivity level 3 (J-STD-020).

Samples are available now, and production quantities on four weeks lead.
