VOFD341A-X009T

Overview

The VOFD341A-X009T is a single-channel MOSFET output optocoupler designed as an IGBT and MOSFET gate driver. It features a 6-SO stretched package with 5000Vrms isolation voltage. The device delivers a peak output current of 3A, with high and low currents rated at 2.5A each. Key electrical parameters include a typical forward voltage of 1.37V, maximum DC forward current of 25mA, and output supply voltage range of 15V to 30V. Propagation delays are maximized at 200ns for both tpLH and tpHL, with pulse width distortion capped at 70ns. Rise and fall times are typically 35ns. It operates between -40°C and +125°C and offers a minimum common-mode transient immunity of 35kV/µs.

Feature Summary

• High-speed switching capability with 35ns typical rise and fall times for efficient gate driving.
• Robust noise immunity provided by 35kV/µs minimum common-mode transient rejection.
• Extended safety clearance achieved through 5000Vrms isolation voltage in a compact surface-mount form factor.

Applications

• IGBT gate drive circuits
• MOSFET gate drive circuits
• Industrial motor control systems

Procurement Notes

Verify the specific suffix X009T against the manufacturer datasheet to confirm packaging configuration and reel specifications. Ensure that the 6-SO stretched package dimensions align with your PCB footprint requirements. Confirm RoHS3 compliance status if required by your manufacturing standards. Cross-reference the UL, cUL, and VDE certification numbers directly from the official Vishay documentation to validate safety approvals for your target market.

Selection Notes

Select this component when high isolation voltage and fast switching speeds are critical for power electronics applications. The 3A peak output current supports direct driving of medium-power IGBTs and MOSFETs without additional buffer stages. Consider the extended operating temperature range for environments subject to thermal stress. The stretched SO-6 package facilitates easier manual assembly or rework compared to standard narrow packages.

Part Context

This part belongs to the VOFD34xA series from Vishay Semiconductor Opto Division, which specializes in compact, high-isolation voltage optocouplers. The series is engineered for demanding industrial applications requiring reliable signal transmission across isolated boundaries. The VOFD341A variant specifically targets gate drive needs, offering a balance of speed and drive strength within a small outline package.

Replacement Considerations

Check for VOFD341A-X018T or VOFD341A-X019T if different packaging options are needed, as these share identical electrical characteristics. Verify pinout compatibility before substituting with other Vishay gate driver optocouplers.
