FOD3150V

Isolators - Gate Drivers Overview

The FOD3150V is a high noise immunity gate drive optocoupler with a 1.0A output current capability, designed to drive most 800V/20A IGBTs and MOSFETs. It features a 5000 Vrms isolation voltage and operates within an extended industrial temperature range of -40°C to 100°C. Key electrical parameters include a maximum propagation delay of 500ns, a pulse width distortion of 300ns, and typical rise/fall times of 60ns. The device supports a wide supply voltage range from 15V to 30V and includes under-voltage lockout (UVLO) with hysteresis for reliable operation.

Isolators - Gate Drivers Feature Summary

• High noise immunity characterized by a minimum common mode rejection of 20kV/µs
• P-channel MOSFET output stage enables output voltage swing close to the supply rail
• Integrated under-voltage lockout (UVLO) with hysteresis ensures stable switching
• Extended industrial temperature range supports operation from -40°C to 100°C

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 'V' indicates the PDIP-8 through-hole package variant when sourcing. Confirm that the component meets UL1577 and IEC60747-5-2 safety standards as documented. Ensure the selected part aligns with the required 5000 Vrms isolation rating for your application's safety clearance needs. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Isolators - Gate Drivers Selection Notes

Select this component when driving 800V class IGBTs or MOSFETs requiring fast switching speeds and high noise immunity. The 1.0A peak output current is sufficient for many standard power modules. Consider the PDIP-8 package for through-hole assembly requirements. Verify that the 15V to 30V supply voltage range matches your gate driver power supply design constraints.

Isolators - Gate Drivers Part Context

The FOD3150V belongs to the FOD3150 series of gate drive optocouplers manufactured by Fairchild Semiconductor, now part of onsemi. This series is engineered for high-performance power system applications where electrical isolation and rapid switching are critical. The 'V' suffix typically denotes the specific packaging configuration, distinguishing it from surface-mount variants like the SDV version.
