RLD65MZT2
RLD65MZT2 is Combination red laser diode manufactured by ROHM.
Features
1) The 10m W of the maximum rating corresponding to DVD-RAM read. 2) Optimization of a strained multi quantum well realizes the reduction in threshold current, and the good temperature characteristic. 3) Low threshold current : 25m A (TC=25°C)。
