NOTES:
1. These ratings are limiting values above which the serviceability of any semiconductor may be impaired.
2. The reverse base-to-emitter voltage must never exceed 6.2 volts; the reverse base-to-emitter current must never exceed 10 µA.
3. Not tested; guaranteed by design.
4. All MIN/TYP/MAX values are absolute numbers. Negative signs indicate electrical polarity only.
