LTV-3120 series
1. DESCRIPTION
The LTV-3120 optocoupler is ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications and
inverters in power supply system. It contains an 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
LTV-3120 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 ~ +105oC.

Notes:
1)
Maximum pulse width = 10μs, maximum duty cycle = 0.2%.
2)
Output is sourced at -2.5 A with a maximum pulse width = 10μs. VCC-VO is measured to ensure 15 V or below.
3)
Output is sourced at 2.5 A with a maximum pulse width = 10μs. VO-VEE is measured to ensure 15 V or below.
4)
In this test VOH is measured with a DC load current. When driving capacitive loads, VOH will approach VCC as IOH
approaches zero amps.
5)
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.
6)
According to UL1577, each photocoupler is tested by applying an insulation test voltage 5250 VRMS for one second
(leakage current less than 10uA). This test is performed before the 100% production test for partial discharge
7)
The difference between TPHL and TPLH between any two LTV-3120 parts under same test conditions.
8)
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.
9)
Common mode transient immunity in low stage is the maximum tolerable positive dV CM/dt on the leading edge of the
common mode impulse signal, VCM, to assure that the output will remain low.
10)
Pulse Width Distortion is defined as TPHL - TPLH for any given device.
11)
At least a 0.1μF or bigger bypass capacitor must be connected/ closed across pin 8 and pin 5. Failure to provide the
bypass may impair the switching property. Normally, it is recommended to place a 1μF multi-layer ceramic capacitor. To
parallel one larger capacitor (>1μF) to optimize performance is better.
