FOD3150T

Isolators - Gate Drivers Overview

The FOD3150T is a single-channel logic output optocoupler from the FOD series, manufactured by onsemi. It features an 8-pin MDIP package designed for through-hole mounting. The device provides high noise immunity and delivers a peak output current of 1.0A, making it suitable for driving IGBTs and MOSFETs up to 800V/20A. Key electrical parameters include a typical rise and fall time of 60ns, an isolation voltage of 5000Vrms, and a maximum forward voltage of 1.8V. It operates within a temperature range of -40°C to 100°C and complies with UL1577 and IEC60747-5-2 standards.

Isolators - Gate Drivers Feature Summary

• High noise immunity for reliable signal transmission in electrically noisy environments
• Capable of driving most 800V/20A IGBT and MOSFET devices directly
• Fast switching performance with 60ns typical rise and fall times

Isolators - Gate Drivers Applications

• Gate drive circuits for IGBTs and MOSFETs
• Industrial motor control systems
• Power supply isolation interfaces

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'T' indicates the tape and reel or bulk packaging variant as defined by onsemi, distinct from other package types like 'TSV'. Confirm RoHS compliance status and check for end-of-life notices, as some variants may be discontinued. Ensure the ordering part number matches the required package style and quantity format specified in the official datasheet.

Isolators - Gate Drivers Selection Notes

Select this component when a high-speed, high-current gate driver optocoupler is required for isolating control signals from power stages. The 1.0A output capability supports direct driving of medium-power switches without external buffers. Consider the 5000Vrms isolation rating for safety-critical applications. Compare against similar FOD series parts if different package styles or slightly lower current ratings are acceptable for cost optimization.

Isolators - Gate Drivers Part Context

The FOD3150T belongs to onsemi's FOD series of high-speed optocouplers. This family is engineered for industrial and consumer applications requiring robust isolation between low-voltage control logic and high-voltage power circuits. The T suffix typically denotes a specific packaging configuration within the broader FOD3150 product line, which includes various DIP and surface-mount options.
