**The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous
voltage rating. For the continuous voltage rating refer to your equipment level safety specication or Avago Application Note 1074 entitled “Op-
tocoupler Input-Output Endurance Voltage.”
Notes:
1. Derate linearly above 70°C free-air temperature at a rate of 0.3 mA/°C.
2. Maximum pulse width = 10 µs, maximum duty cycle = 0.2%. This value is intended to allow for component tolerances for designs with I
O
peak
minimum = 2.0 A. See Applications section for additional details on limiting I
OH
peak.
3. Derate linearly above 70°C free-air temperature at a rate of 4.8 mW/°C.
4. Derate linearly above 70°C free-air temperature at a rate of 5.4 mW/°C. The maximum LED junction tem-perature should not exceed 125°C.
5. Maximum pulse width = 50 µs, maximum duty cycle = 0.5%.
6. In this test V
OH
is measured with a dc load current. When driving capacitive loads V
OH
will approach V
CC
as I
OH
approaches zero amps.
7. Maximum pulse width = 1 ms, maximum duty cycle = 20%.
8. In accordance with UL1577, each optocoupler is proof tested by applying an insulation test voltage ≥4500 Vrms for 1 second (leakage detec-
tion current limit, I
I-O
≤ 5 µA).
9. In accordance with UL1577, each optocoupler is proof tested by applying an insulation test voltage ≥4500 Vrms for 1 second (leakage detec-
tion current limit, I
I-O
≤ 5 µA).
10. In accordance with UL1577, each optocoupler is proof tested by applying an insulation test voltage ≥6000 Vrms for 1 second (leakage detec-
tion current limit, I
I-O
≤ 5 µA).
11. Device considered a two-terminal device: pins 1, 2, 3, and 4 shorted together and pins 5, 6, 7, and 8 shorted together.
12. The dierence between t
PHL
and t
PLH
between any two HCPL-3120 parts under the same test condition.
13. Pins 1 and 4 need to be connected to LED common.
14. Common mode transient immunity in the high state is the maximum tolerable dV
CM
/dt of the common mode pulse, V
CM
, to assure that the
output will remain in the high state (i.e., V
O
> 15.0 V).
15. Common mode transient immunity in a low state is the maximum tolerable dV
CM
/dt of the common mode pulse, V
CM
, to assure that the out-
put will remain in a low state (i.e., V
O
< 1.0 V).
16. This load condition approximates the gate load of a 1200 V/75A IGBT.
17. Pulse Width Distortion (PWD) is dened as |t

| for any given device.
