Features
Description
• 2.5A Maximum Peak Output Current
• 25kV/µs Minimum Common Mode Rejection (CMR)
The IX3120 gate driver includes an input infrared LED
that is optically coupled to a power output stage. The
power output stage is capable of sourcing or sinking
2A of peak current, which is ideal for driving IGBTs
and MOSFETs in the mid-power range.

• Wide Operating Voltage Range: 15V to 30V
• Under Voltage Lockout with Hysteresis
• 3750V
Input to Output Isolation
rms
The gate driver optocoupler with its low input LED
current, high output peak current, and high noise
immunity (25kV/s) is ideally suited for use in motor
control and inverter applications.
• Wide Temperature Range: -40°C to +100°C
Applications
• Isolated IGBT/MOSFET Gate Drive
• Switch Mode Power Supplies
• Industrial Inverters
The IX3120 is provided in an 8-pin DIP package and
an 8-pin surface mount package.
• Motor Drivers
Approvals
• UL Recognized Component: File E76270
• IEC/EN/DIN EN 60747-5-5 (“GE” Versions)
