2.5A Output Current, High CME
Gate Drive Optocoupler
ICPL-3120
Description
The ICPL3120 optocoupler is ideally suited
for driving power IGBTs and MOSFETs used
in motor control inverter applications and
inverters in power supply system. It contains
a AlGaAs LED optically coupled to an
integrated circuit with a power output stage.
The 2.5A peak output current is capable of
directly driving most IGBTs with ratings up to
1200 V/100 A. For IGBTs with higher ratings,
the ICPL3120 series can be used to drive a
discrete power stage which drives the IGBT
gate.
The Optocoupler operational parameters
are guaranteed over the temperature range
from -40oC ~ +110oC.
Features
• 2.5 A maximum peak output current
• 25 kV/us minimum Common Mode Rejection
(CMR) at VCM = 1500 V
• 3.8 mA maximum supply current (ICC)
• Under Voltage Lock-Out protection (UVLO) with
hysteresis
• Wide operating range: 15 to 30 Volts (VCC)
• Guaranteed performance over temperature
-40oC ~ +110oC.
• Offer low power dissipation with RON ≤ 1Ω
• Fast switching speed, 500ns max propagation
delay
• Safety approval: UL, cUL, VDE (In process)
Application
• IGBT/MOSFET gate drive
• Uninterruptible power supply (UPS)
• Industrial Inverter
• Induction heating

Notes:
1) Maximum pulse width = 10us, maximum duty cycle = 0.2%.
2) Device is considered a two terminal device: pins 1, 2, 3 and 4 are shorted together and pins 5, 6,
7 and 8 are shorted together.
3) According to UL1577, each optocoupler is tested by applying an insulation test voltage ≥ 6000
Vrms for 1 second (leakage detection current limit, II-O ≤ 6 uA).
4) The difference between TPHL and TPLH between any two ICPL3120 parts under same test
conditions.
5) Common mode transient immunity in high stage is the maximum tolerable negative dVcm/dt on
the trailing edge of the common mode impulse signal, Vcm, to assure that the output will remain
high.
6) Common mode transient immunity in low stage is the maximum tolerable positive dVcm/dt on the
leading edge of the common mode impulse signal, Vcm, to assure that the output will remain low.
7) Pulse Width Distortion is defined as |TPHL - TPLH| for any given device.
