TO18 5.6mm Packsge 980nm 50mW Invisible Laser Diode
The ROHM RLD980050 is a compact, low-power 980nm laser diode, tailored for small-scale optoelectronic setups like precision sensors or compact optical modules. First, its design centers on practical integration: it’s housed in a standard TO-18 (φ5.6mm) package, complete with a lead-free glass cap, and even includes a built-in PIN photodiode (PD) — this means real-time power monitoring is built right in, cutting down on alignment work for precision applications.
When it comes to performance, the diode delivers a steady 50mW optical output at 980nm (invisible light), paired with a 2V reverse voltage rating (and 30V for the integrated PD). To ensure reliability across use cases, it operates smoothly between -10 to +40°C and tolerates storage temperatures from -15 to +85°C — making it sturdy enough for both portable gadgets and fixed-module setups.
Finally, its compact TO-18 form factor (with clearly defined dimensional specs) means it fits easily into space-constrained designs. Whether you’re building a small sensor or a tight optical module, this 980nm 50mW laser diode blends ROHM’s dependable engineering, built-in monitoring, and small size to tick the boxes for low-power optoelectronic needs.
