Rohm 4-pin LED lights have new thermal design

Rohm Semiconductor has a high brightness 4-pin PLCC4 LED range of devices with operating temperature range (-40°C to 100°C) with improved derating characteristics compared to PLCC 2 packages, writes Richard Wilson.

A gold-plated frame is utilized for superior sulfuration resistance.

There are three different models:
- the large current type SML-Y17U2T with a maximum driving current of 150mA
- the high efficiency type SML-Y16U2T (IF max 70mA)
- the standard type SML-Y15U2T (IF max 70mA).
