VOFD341A-X019T

Overview

The VOFD341A-X019T is a single-channel IGBT and MOSFET driver optocoupler manufactured by Vishay Semiconductor Opto Division. It features a peak output current of 3A with continuous high/low currents of 2.5A. The device provides 5000Vrms isolation voltage and operates within a temperature range of -40°C to 125°C. Key electrical parameters include a maximum propagation delay of 200ns, a minimum common-mode transient immunity of 35kV/µs, and an output supply voltage range of 15V to 30V. It utilizes a 6-SO stretched package.

Feature Summary

• High-speed optical coupling designed for direct driving of IGBTs and MOSFETs
• Robust insulation capability with 5000Vrms isolation voltage rating
• High common-mode transient immunity to prevent false triggering in noisy environments
• Rail-to-rail output stage ensuring efficient power switch control

Applications

• Direct driving of IGBTs with ratings up to 1200V/100A
• Solar inverters and photovoltaic systems
• Industrial motor drives and power supplies

Procurement Notes

Verify the specific suffix X019T against official Vishay documentation to confirm packaging and reel specifications. Ensure compatibility with system isolation requirements and thermal management needs. Cross-reference datasheet revisions to confirm pinout consistency. Confirm RoHS compliance status matches project regulatory standards before finalizing procurement orders.

Selection Notes

Select this component when high-speed switching and robust noise immunity are required for medium-power IGBT applications. The 3A peak drive current supports direct gate control without additional buffer stages. Consider the 6-SO stretched package for PCB layout constraints. Evaluate the 5000Vrms isolation rating against system safety standards and creepage/clearance requirements.

Part Context

This part belongs to the VOFD34xA series of MOSFET output optocouplers from Vishay. The series is engineered specifically for industrial power electronics, offering a balance of speed and isolation. The VOFD341A variant focuses on single-channel applications, providing a compact solution for gate drive circuits where space and performance are critical factors.

Replacement Considerations

Check for VOFD341A-X009T or VOFD341A-X018T as potential variants within the same family. Verify if alternative suffixes indicate different packaging options rather than functional changes. Ensure any substitute maintains the 3A peak current and 5000Vrms isolation ratings.
