IXYS IX3407B Isolated Single-Channel IGBT Gate Driver
The IX3407B features separate outputs built-in under voltage lockout and active shutdown
The IX3407B capacitively isolated gate driver by IXYS, provides basic galvanic isolation between the low voltage control side and the high voltage driver side. This ensures proper function of the equipment, alleviating the challenge of direct electrical connection between the control logic and the power semiconductor.
This ensures proper function of the equipment, helping to drive high power devices that require fast and clean signals. IXYS’ IX3407B’s proprietary capacitive isolation technology enables fast digital signalling, low propagation delays, short rise/fall times and high common mode transient immunity (CMTI). The IX3407B enables compact gate drive designs with fewer external components, ensuring long-term reliability and high performance.
IX3407B Features
- Separate source and sink pin up typical 7APK

- CMTI value of 150kV/μs
Benefits
- Easy to optimise switching performance
- Supports a wide range of control logic devices
- Drives a variety of Si/SiC MOSFETs and IGBTs
- No separate galvanic isolation IC needed
- Protects driver IC and power stage
- Robust operation
Applications
- Switched-mode power supplies
- Industrial motor drives
- Industrial power supplies
The IX3407B gate driver often drives power switches like IGBTs or SiC MOSFETs via an isolated supply. A bridge rectifier is likely required in the auxiliary supply path from a transformer secondary feeding a smoothing capacitor to generate the isolated gate voltage.
Determine the size of the rectifier:
- Determine the AC input voltage feeding the IX3407B’s auxiliary section.
- Calculate the required DC current (including control circuits or bias).
- Apply the 2.5x rule to both voltage and current to choose your rectifier margin
- Select a VF that keeps dissipation low and ensure you have proper heat sinking if needed.
- Choose the appropriate packaging (for example, through-hole DIP for prototyping vs. SMD for compact production).
