Notes for Table 4:
1. Proper current derating must be observed to maintain junction temperature below the maximum. For additional information on thermal measurement guidelines please
refer to Application Brief AB118 (not available yet).
2. Residual periodic variations due to power conversion from alternating current (AC) to direct current (DC), also called “ripple”, with frequencies
≥
100 Hz and amplitude
≤
150 mA are acceptable, assuming the average current throughout each cycle does not exceed 1050 mA.
3. Pulsed operation with a peak drive current of 1200 mA is acceptable if the pulse on-time is
≤
5 ms per cycle and the duty cycle is
≤
50%
4. Transient reverse voltages and surge currents due to electrical switching or supply interruptions are acceptable if these events do not last for more than 10ms, the
amplitude of the reverse voltage does not exceed 5V and the reverse current is less than 200μA.
5. Max 5V reverse for up to 10s is an acceptable beginning of life, one time test condition.
