DMP1KKM is a 905 nm, 16-channel linear VCSEL array in a 17.3 × 4.0 × 1.7 mm AlN ceramic package. Each channel is characterized at 70 W typical peak power with a 15 A, 1.5-2 ns pulse and 0.03% duty cycle at 25 °C.
Key Highlights
The DMP1KKM is a 905 nm VCSEL emitter built as a 16-channel linear array in an AlN ceramic package measuring 17.3 × 4.0 × 1.7 mm. The datasheet identifies surveillance systems, LiDAR and autopilot, and machine vision systems as target applications.
Each channel is characterized at 25 °C with a 15 A drive current, 1.5-2 ns pulse width and 0.03% duty cycle. At that test point, peak optical power is 70 W typical and 40 W minimum, while peak wavelength is 905 nm typical across a specified 895-915 nm range. These are per-channel pulsed measurements, not total-array output or continuous-wave ratings.
Use the published package outline, recommended pad pattern and circuit diagram for PCB integration. System range, accuracy, illumination uniformity, receiver compatibility, thermal performance and laser-safety classification are not specified in this datasheet and must be validated in the complete product.
The electro-optical table specifies 70 W typical and 40 W minimum peak power per channel at 15 A, 1.5-2 ns and 0.03% duty cycle. The same operating point gives 20.5 V typical forward voltage, 4.9 W/A typical slope efficiency and 0.7-0.9 Ω series resistance as published.
Peak wavelength is specified from 895 to 915 nm with a 905 nm typical value. Maximum spectral bandwidth is 3.0 nm and maximum beam divergence is 24° using the datasheet’s full-width D86 definition, all under the stated per-channel pulse condition.
The 17.3 × 4.0 × 1.7 mm package combines a 16-channel line-array format with an AlN ceramic construction. The mechanical drawing specifies ±0.2 mm tolerance and includes a recommended PCB pad pattern plus a numbered 1-16 circuit diagram.
The following application categories are listed in the DMP1KKM specification. Final optical, electrical, thermal and safety performance depends on the complete system design.

Yes. The datasheet specifies 70 W typical and 40 W minimum peak optical power for each channel at T = 25 °C, If = 15 A, a 1.5-2 ns pulse width and 0.03% duty cycle. It does not specify total-array optical output.
Yes. DMP1KKM is a 16-channel linear VCSEL array. Peak wavelength is 905 nm typical, with a specified 895-915 nm range per channel at the published pulse test condition.
Yes. The product specification lists LiDAR and autopilot, machine vision systems and surveillance systems as target applications. Range, accuracy, receiver compatibility, illumination uniformity and eye safety must still be validated in the complete system.
Yes. Its electro-optical characteristics are specified at a 1.5-2 ns pulse width and 0.03% duty cycle. The absolute maximum forward-current rating is 30 A per channel at Tp = 2.0 ns, DC = 0.03% and Ts = 25 °C; this limit is not a recommended operating point.
Yes. The datasheet provides a Pb-free SnAgCu profile with a 260 °C peak package-body temperature, 217 °C liquidus temperature and the published ramp and dwell limits. The device remains ESD/EOS sensitive, so grounded handling, surge protection and an ESD-controlled production environment are required.
