0 When forming the leads, be careful not to apply stress to the main body of the device (the resin
part). Soldering must be performed after the leads have been formed.
0 The collector current increases over time due to current flowing in the infrared LED. The design
of circuits which incorporate the device must take into account the change in collector current
over time. The change in collector current is equal to the reciprocal of the change in LED infrared
optical output.
