Laser Diode in TO-220 Package with FC-connector 0.75 W cw (Class 4 Laser Product)

Siemens AG 

SPL 2Fxx

(SFH 4874x6)

Notes for Operation

1. Eye Protection

This laser is a Class 4 Laser product.

Refer to the relevant safety regulations for protection during handling and operation.

2. Overload Protection

The specified values are valid as long as the diode has not been not overloaded. Voltage

spikes from the power supply unit, even when applied for nanoseconds only, may cause irre-

versible damage to the laser diode. Such spikes may occur when the power supply is turned

on or off, or they may reach the laser diode from the line via the coupling capacitance of

electronically controlled devices.

The power supply should therefore be provided with appropriate protection circuits.

Handling Notes

1. Package

To avoid electrostatic damage it is recommended to observe the same rules as for handling

MOS-devices.

2. Mechanical Attachment

2.1 Mounting hole (suitable for M 2.5)

Because of the good thermal conductivity of the TO 220 base plate (copper) the heat

loss is properly dissipated even if the component is attached on one side only. Some

mounting techniques are shown below (Fig. 1 – 3).

2.2 For exact positioning of the TO component and other parts, e.g. lenses, the TO 220

package can be attached with appropriate clamping devices or screws (max. M 2.5).

3. Soldering

When soldering the TO base to a heat sink, do not exceed the following limits:

• max. soldering temperature: 125 °C

• max. soldering time:

1 min.
