The XL-PLPT5 635B-10mW is a single-mode semiconductor laser, enclosed in a TO56 package (with a built-in photodiode). It typically emits at 637nm (red light) and has a continuous-wave (CW) output power of 10mW (TC=25°C). This device can operate in both CW and pulsed modes, offers high modulation bandwidth, and is ideal for applications requiring higher-power red light like indicators, alignment, sensing, and measurements. It meets ROHS environmental standards, has a moisture sensitivity level of MSL 2, and has passed multiple reliability tests.
