FOD3184

Isolators - Gate Drivers Overview

The FOD3184 is a high-speed MOSFET and IGBT gate drive optocoupler featuring a 3A output current capability. It utilizes an AlGaAs LED for isolation, providing 5000Vrms insulation voltage. The device operates within a temperature range of -40°C to +100°C and supports supply voltages from 15V to 30V. Key electrical parameters include a maximum forward current of 25mA, typical rise and fall times of 38ns and 24ns respectively, and a minimum common-mode transient immunity of 35kV/µs. Propagation delays are capped at 210ns.

Isolators - Gate Drivers Procurement Notes

Verify the specific package variant required, as the FOD3184 family includes through-hole DIP-8 (e.g., FOD3184) and surface-mount SOIC-8 (e.g., FOD3184SDV) options. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding assembly or material updates before finalizing procurement orders.

Isolators - Gate Drivers Selection Notes

Select this component when designing circuits that demand fast switching speeds and high noise immunity for power devices. Ensure the input current does not exceed the 25mA maximum limit. Verify that the system's isolation requirements align with the 5000Vrms rating and that the operating temperature range fits the application environment.

Isolators - Gate Drivers Part Context

The FOD3184 belongs to the FOD318 series of gate driver optocouplers manufactured by onsemi. This series is engineered specifically for driving power semiconductors in demanding applications.
