Recommended soldering conditions • Peak Temperature 350°C or below • Time 3 seconds or less • Soldering of leads should be made at the point 2.0 mm from the root of the lead • This device cannot be mounted using reflow soldering. 2. Usage cautions (1) Take the following steps to ensure that the device is not damaged by static electricity. • Wear an antistatic wrist strap when soldering the device. We recommend a strap with a 1 MΩ resistor. • Make sure that the work table and soldering iron are grounded. • Make sure that the soldering iron does not leak. (2) Do not subject the package to undue stress. The package has a tensile strength of 1N. Do not exceed this rating. Also, avoid bending the leads as much as possible. If the leads must be bent, bend them only once, making sure to anchor the base of the lead. (3) Do not allow the glass window of the package to become scratched or dirty. Also, do not subject the glass window to external force. (4) Be sure to attach a heat sink to sufficiently dissipate heat. (5) Use the device as soon as possible after opening the aluminum moisture barrier bag.

If the laser beam or its reflection enters your eye, it may cause injury to the eye or loss of eyesight. (Note that, depending on the wavelength of the beam, the laser beam might not be visible.) • Do not look directly into the laser beam. • Avoid exposure to the laser beam, any reflected or collimated beam.
