ROHM TO18-5.6mm Packaged 635nm 5mW Laser Diode With a Built-in P.D.
This ROHM RLD63NPC5-00B is a compact, TO18-5.6mm packaged red laser diode—featuring a built-in PIN photodiode (PD)—designed for applications like leveling, sensors, ranging, and barcode readers. It leverages an InGaAlP double-hetero structure to deliver reliable 5mW optical output at a 635nm dominant wavelength (range: 630–640nm), ideal for precise visible red emission.
Core Specifications (at 25°C Case Temperature):
- Electrical Performance: Operates with a typical 2.2V forward voltage (max 2.7V) and 33mA operating current (max 45mA) at 5mW output; the threshold current is typically 24mA (max 35mA). It also includes a built-in PD with a 20V reverse voltage rating.
- Optical Characteristics: Offers controlled beam divergence (typical 8° parallel, 32° perpendicular—full width at half maximum) and tight beam tolerance (±2° parallel, ±3° perpendicular), ensuring focused, consistent beam alignment. The emission point accuracy stays within ±100μm for precision use cases.
- Durability & Operation: Functions reliably in -10–40°C operating temperatures (storage range: -40–85°C). The module’s monitor current varies by type (0.11–0.23mA, across D/G ranks) to suit different application needs.
With its compact TO18 form factor, built-in PD for feedback, and stable performance, this ROHM laser diode balances precision, reliability, and ease of integration—perfect for industrial and consumer devices requiring low-power, accurate red laser output.
