Photocoupler
LTV-3120 series
3.0 Amp Output Current IGBT Gate Drive Optocoupler with Rail-to-Rail Output
Voltage, High CMR.
1. DESCRIPTION
The LTV-3120 series Photocoupler 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 3.0A 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 Photocoupler operational parameters are guaranteed over the temperature range from -40oC ~ +110oC.

Note: Ambient temperature = 25oC, unless otherwise specified. Stresses exceeding the absolute maximum
ratings can cause permanent damage to the device. Exposure to absolute maximum ratings for long periods of
time can adversely affect reliability.
Note: Note: A ceramic capacitor (0.1 μF) should be connected between pin 8 and pin 5 to stabilize the
operation of a high gain linear amplifier. Otherwise, this Photocoupler may not switch properly. The bypass
capacitor should be placed within 1 cm of each pin.
Note 1: Pulse width (PW) ≤ 1 μs, 300 pps
Note 2: Exponential waveform. Pulse width ≤ 0.3 μs, f ≤ 15 kHz
Note 3: The rise and fall times of the input on-current should be less than 500 ns

Note 2: According to UL1577, each Photocoupler is tested by applying an insulation test voltage 6000VRMS for one second (leakage
current less than 10uA). This test is performed before the 100% production test for partial discharge
