PERFORMANCE CHARACTERISTICS
1. Climatic Category :
55/125/56 acc. to IEC
11. Permissible AC Voltage Stress :
The highest
permissible AC voltage for the respective frequency may
be taken from the brochure 鈥淕eneral information鈥?
The values apply for + 20擄C For higher temperatures,
the values have to be multiplied with the following
factors :
TEMPERATURE
+ 50擄C
+ 85擄C
+ 125擄C.

2. Temperature Range :
- 55擄C up to + 125擄C. with linear
voltage derating to category voltage UC
3. Rated Voltage, Category Voltage :
3V_ to 50V_;
2V_ to 33V_
4. Surge Voltage :
1.3 times of rated voltage at + 85擄C
5. Reverse voltage (Temporarily) :
15% of the rated DC voltage at + 20擄C
10% of the rated DC voltage at + 55擄C
5% of the rated DC voltage at + 85擄C
Intermediate values can be obtained by linear
interpolation. For further notes on AC voltage stress :
