To avoid stress cracking, we suggest using
ND Industries’ Vibra-Tite for thread-locking.
Vibra-Tite evaporates fast without causing structural failure in
OPTEK'S molded plasꢁcs.

Notes:
1. RMA flux is recommended. Duraꢁon can be extended to 10 seconds maximum when flow soldering. A maximum 20 grams force may be applied
to the leads when soldering.
2. For OP550, OP560 and OP555, derate linearly 1.33 mW/° C above 25° C. For OP552, derate linearly 1.25 mW/° C above 25° C.
3. For all phototransistors in this series, the light source is an unfiltered GaAs LED with a peak emission wavelength of 935 nm. For OP550 and
OP555 only, a radiometric intensity level that varies less than 10% over the enꢁre lens surface of the phototransistor being tested applies.
4. To calculate typical collector dark current in µA, use the formula ICEO=10 (0.040 T - 3.4), where TA is ambient temperature in ° C.
