The DMP300KP is a 905 nm pulsed VCSEL in a 5.2 × 5.2 × 1.55 mm AlN ceramic package. At Ts = 25 °C and IF = 61 A, the datasheet specifies 300 W typical optical output at a 5 ns pulse width and 0.025% duty cycle, with 40° horizontal × 30° vertical typical beam divergence.
Key Highlights
Designed for nanosecond-pulsed illumination, the DMP300KP addresses the ToF and 3D-sensing use cases named in the datasheet, including object avoidance, people-flow and volume measurement, gesture recognition, AR/VR and night vision. Its 40° horizontal × 30° vertical typical emission pattern provides a starting point for transmitter-optics design, but the datasheet does not define the divergence measurement convention or angular tolerance; confirm beam coverage with production samples.
For electrical and thermal integration, treat the published IF = 61 A, Tp = 5 ns and 0.025% duty-cycle condition as a characterization point rather than a general drive recommendation. The corresponding 300 W optical output is typical at Ts = 25 °C, while the absolute maximum table separately lists a 50 ns pulse-duration limit and 0.05% duty-cycle limit. Because recommended repetition rate, peak-current limit, junction temperature, thermal resistance and laser class are not specified, qualify driver margin, PCB thermal performance and optical safety in the final assembly.
The source specification lists night vision, ToF, gesture recognition, people-flow statistics, volume measurement, 3D scanning, avoidance and AR/VR. The following application groupings keep those stated use cases while identifying the system-level work still required.
The values below reproduce the DMP300KP Rev1.0 specification. Typical values are not guaranteed maxima, and the 300 W output applies only to the stated pulsed test condition.

The DMP300KP provides 300 W typical pulsed optical output at Ts = 25 °C, IF = 61 A, a 5 ns pulse width and 0.025% duty cycle. Under the same condition, the typical forward voltage is 25 V and the typical power-conversion efficiency is 20%.
The DMP300KP is specified as a pulsed VCSEL. The 300 W characteristic is measured at a 5 ns pulse width and 0.025% duty cycle. The absolute maximum ratings list 50 ns pulse duration and 0.05% duty cycle; continuous-wave operation is not specified.
Yes. The datasheet explicitly lists ToF, volume measurement and 3D scanning among the target applications. The 905 nm wavelength, 300 W typical pulsed output and 40° × 30° typical divergence provide defined emitter inputs, while range, accuracy and ambient-light performance must be validated in the complete system.
Peak wavelength is 895-915 nm with a 905 nm typical value. The datasheet reports 40° horizontal × 30° vertical typical beam divergence, 4 nm maximum spectral width and a 0.07 nm/°C typical wavelength coefficient under the stated pulse condition. The divergence convention and tolerance are not stated, so confirm them before optical tooling release.
Yes. The 5.2 × 5.2 × 1.55 mm AlN ceramic package includes a center pad marked N.C., and the datasheet states that this pad may be used as a thermal pad. Board-level copper, vias, attachment process and thermal performance still require validation for the intended pulse train.
The specified operating-temperature range is -20 to 85 °C and the storage range is -40 to 85 °C. The datasheet requires ESD and EOS precautions, surge protection, proper grounding and an ESD-controlled handling environment. It also provides a Pb-free SnAgCu reflow profile with a 260 °C peak package-body temperature.
