FOD3150

Isolators - Gate Drivers Overview

The FOD3150 is a high noise immunity gate drive optocoupler with a 1.0A output current, capable of driving most 800V/20A IGBTs and MOSFETs. It features a gallium aluminum arsenide LED optically coupled to a high-speed push-pull driver IC. Key electrical parameters include a minimum common mode rejection of 20kV/µs, a maximum propagation delay of 500ns, and a pulse width distortion of 300ns. The device operates with a supply voltage range of 15V to 30V and supports an extended industrial temperature range from -40°C to 100°C.

• Integrated Under Voltage LockOut (UVLO) with hysteresis for reliable operation
• Fast switching speed with low propagation delay and pulse width distortion

Isolators - Gate Drivers Applications

• Industrial inverter systems
• Uninterruptible power supplies (UPS)
• Induction heating equipment
• Isolated IGBT and power MOSFET gate drive circuits

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix on the part number to confirm package type and tape/reel configuration. Ensure compliance with RoHS directives if required for your assembly process. Check for recent Product Change Notifications regarding material suppliers or design layouts. Confirm that the safety approvals meet the specific regulatory requirements of your target market before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when driving IGBTs or MOSFETs up to 800V requires high noise immunity and fast switching speeds. The 1.0A output current is suitable for most standard power devices in motor control and inverter applications. Consider the UVLO feature for systems requiring robust protection against undervoltage conditions during startup or fault states.

Isolators - Gate Drivers Part Context

The FOD3150 belongs to the FOD3150 family of gate drive optocouplers manufactured by onsemi, formerly Fairchild Semiconductor. It is designed as a replacement for legacy isolation drivers in high-performance power systems. The device provides galvanic isolation between control logic and power switches, ensuring signal integrity in noisy environments typical of industrial power electronics.
