VISIBLE LASER DIODE
NDL3321ST,NDL3321SU
5 mW, 650 nm AlGaInP MQW VISIBLE LASER DIODE FOR DVD, DVD-ROM APPLICATIONS
DESCRIPTION
t The NDL3321ST and NDL3321SU are AlGaInP 650 nm visible laser diodes and especially developed for DVD,
DVD-ROM. The newly developed Multiple Quantum Well (MQW) LD chip, can achieve low operating current, wide
c temperature range.
Use of a CD package allows easy replacement of conventional 780 nm LDs.
