FOD3150SD

Isolators - Gate Drivers Overview

The FOD3150SD is a single-channel optically coupled gate driver manufactured by onsemi, designed for driving MOSFETs, IGBTs, and SiC devices. It features a peak output current of 1.5A with continuous high/low currents of 1A each. The device provides 5000Vrms isolation voltage and operates within a supply voltage range of 15V to 30V. Key electrical specifications include a maximum propagation delay of 500ns for both rising and falling edges, a pulse width distortion of 300ns maximum, and a typical rise/fall time of 60ns. It exhibits a minimum common-mode transient immunity (CMTI) of 20kV/µs. The component is housed in an 8-SMD package and supports an operating temperature range from -40°C to 100°C.

Isolators - Gate Drivers Feature Summary

• Provides robust galvanic isolation between control circuitry and power switches using optical coupling technology.
• Delivers sufficient peak drive current to effectively switch high-power semiconductor devices such as IGBTs and SiC FETs.
• Ensures signal integrity in noisy environments through high common-mode transient immunity capabilities.

Isolators - Gate Drivers Applications

• Industrial power supplies
• Photovoltaic inverters
• DC motor control systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'SD' corresponds to the surface-mount 8-SMD package variant when sourcing components. Confirm that the required isolation rating meets the application's safety standards, as this model specifies 5000Vrms. Ensure the input forward current limits are respected within the design parameters to maintain device longevity and performance stability.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel gate driver with high isolation voltage is required for power electronics applications. It is suitable for designs needing moderate peak drive currents up to 1.5A. Consider the 8-SMD package constraint for PCB layout compatibility. Evaluate the 500ns propagation delay against switching frequency requirements to ensure adequate timing margins for the target power stage.

Isolators - Gate Drivers Part Context

This part belongs to the FOD3150 series of optocoupler gate drivers from onsemi. The series is engineered for reliable operation in demanding industrial and automotive environments. The 'SD' designation specifically identifies the surface-mount version, distinguishing it from through-hole variants like the FOD3150V. These drivers are integral to modern power conversion topologies requiring isolated control signals.
