current and the good temperature characteristic.
!Applications
DVD-ROM
COMBINATION Drive
Sensors
!Features
1) The 10mW 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 : 25mA (TC=25°C)
