KY-008 Laser 650nm 5V Laser Diode Laser Transmitter
A laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively.

Q & A
Ask a question
Son is working on a project but the spec sheet for the Laser needs how it is classed with the FDA to us it.. do you have that information
A 650nm 5V laser diode typically emits red light at 650 nanometers (nm) and operates at 5 volts (V). When considering FDA class, laser diodes fall under different safety classifications depending on their power output and intended use.
FDA Laser Classifications:
Class 1: Safe under normal operation (e.g., CD/DVD players).
Class 2: Low-power visible lasers (≤1 mW) that rely on the blink reflex for safety.
Class 3R (formerly Class 3A): Medium-power lasers (1–5 mW), potentially hazardous if stared at directly.
Class 3B: Higher power (5–500 mW), can cause eye damage with direct exposure.
Class 4: High-power lasers (>500 mW), dangerous to eyes and skin.
If your 650nm 5V laser diode is a common module used in laser pointers, barcode scanners, or alignment tools, it likely falls under Class 2 or Class 3R, assuming its power output is ≤5mW. If it's a higher-powered module (e.g., 100mW+), it could be Class 3B or 4, requiring safety precautions.
