FOD3120SV

Isolators - Gate Drivers Overview

The FOD3120SV is a single-channel gate drive optocoupler manufactured by onsemi, formerly Fairchild Semiconductor. It features a push-pull output stage capable of delivering a maximum continuous output current of 2.5 A. The device provides high noise immunity with a minimum common mode rejection of 35 kV/µs and supports a wide supply voltage range from 15 V to 30 V. Key electrical parameters include a maximum propagation delay of 400 ns, rise and fall times of 60 ns each, and an insulation voltage of 5000 Vrms. It operates within an extended industrial temperature range of -40°C to +100°C and utilizes an SMT-8 surface mount package.

Isolators - Gate Drivers Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm that the received part matches the specific FOD3120SV designation and packaging format. Check for valid RoHS compliance documentation and safety certification marks as specified in the official datasheet. Ensure storage conditions adhere to manufacturer guidelines to maintain device integrity prior to assembly.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring fast switching speeds and high peak output current capabilities. The integrated UVLO feature ensures protection against low supply voltage conditions. Consider the SMT-8 package for space-constrained designs. Verify that the required insulation voltage and common mode rejection levels meet the specific isolation requirements of the target circuit topology.

Isolators - Gate Drivers Part Context

The FOD3120SV belongs to the FOD3120 series of gate drive optocouplers. This series is designed to drive medium-power IGBTs and MOSFETs, typically rated up to 1200V/20A. The device replaces older discrete driver solutions by integrating the optocoupler and gate driver into a single compact package, simplifying design and improving performance in high-frequency power conversion applications.
