Summary of OSRAM OPTO SEMICONDUCTORS SPL SXL90A LIDAR QFN PACKAGED SMT LASERS
Osram SPL SxL90A LiDAR QFN packaged SMT lasers are 905nm, AEC-Q102 automotive-qualified high-power pulsed infrared SMT lasers (single- and four-channel) delivering up to 125W per channel, 480W total (four-channel), efficiencies up to 33%, low thermal resistance (31K/W single, 17K/W four-channel), compact QFN packages, and ~2ns pulse widths for extended LiDAR detection range.
Parts used in the Osram SPL SxL90A LiDAR project:
- Osram SPL S1L90A_3 A01 single-channel pulse laser (QFN packaged SMT)
- Osram SPL S4L90A_3 A01 four-channel pulse laser (QFN packaged SMT)
- QFN SMT package (for laser modules)
- Thermal management/heat sink interface (implied by low Rth requirements)
- Drive circuitry capable of 40A pulse current per channel
- Pulse control for ~2ns pulse widths
- Optical integration components for 905nm LiDAR systems (lenses, emit/receive optics) (implied)
Osram SPL SxL90A LiDAR QFN Packaged SMT Lasers are infrared high-power SMT components for LiDAR (Light Detection and Ranging) applications. This allows autonomous vehicles to “see” farther and more effectively.
The AEC-Q102 qualified four-channel and single-channel pulse lasers offer a performance of 125W at 40A per channel and an efficiency of up to 33%. The single-channel-version (SPL S1L90A_3 A01) offers low thermal resistance of 31K/W, whereas the four-channel device (SPL S4L90A_3 A01) offers just 17K/W. This makes it easy for heat to dissipate from the components even at high currents.
The four-channel version features a chip with four emission areas that deliver an outstanding optical power at 480W. The laser enables a much longer detection range at a size of just 3.35mm x 2.45mm x 0.65mm. This makes it only slightly larger than the single-channel-version of size 2.0mm x 2.3mm x 0.65mm. The two high-power SMT lasers also enable short pulse widths of around 2ns.
