Description
The HCPL-3120 consists of a
GaAsP LED optically coupled to
an integrated circuit with a power
output stage. This optocoupler is
ideally suited for driving power
IGBTs and MOSFETs used in
motor control inverter applica-
tions. The high operating voltage
range of the output stage pro-
vides the drive voltages required
by gate controlled devices. The
voltage and current supplied by
this optocoupler makes it ideally
suited for directly driving IGBTs
with ratings up to 1200 V/100 A.
For IGBTs with higher ratings,
the HCPL-3120 can be used to
drive a discrete power stage
which drives the IGBT gate.
A 0.1
µ
F bypass capacitor must be connected between pins 5 and 8.
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component
to prevent damage and/or degradation which may be induced by ESD.

maximum duty cycle = 0.2%. This
value is intended to allow for

Applications section for additional
details on limiting I

4. Derate linearly above 70

6. In this test V
OH
is measured with a dc

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
≥
3000 Vrms for 1 second (leakage
detection current limit, I
I-O
≤

A).
This test is performed before the
100% production test for partial
discharge (method b) shown in the
VDE 0884 Insulation Characteristic
Table, if applicable.

device: pins 1, 2, 3, and 4 shorted

shorted together.
10. The difference between t

and t
PLH
between any two HCPL-3120 parts
under the same test condition.
11. Pins 1 and 4 need to be connected to
LED common.
12. 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

13. 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 output will
remain in a low state (i.e., V
O
< 1.0 V).
14. This load condition approximates the
gate load of a 1200V/75A IGBT.
