RLD65MZT1
RLD65MZT1 is DVD-ROM red laser diode manufactured by ROHM.
Features
1) Optimization of a strained multi quantum well realizes the reduction in threshold current, and the good temperature characteristic. 2) Low threshold current : 25m A (TC=25°C) 3) Low noise is realized by a high frequency modulation element..
