FOD3180SD

Isolators - Gate Drivers Overview

The FOD3180SD is a high-speed MOSFET gate driver optocoupler manufactured by onsemi, originally developed by Fairchild Semiconductor. It features a single channel with push-pull output configuration in an SMD-8 package. Key electrical parameters include a maximum continuous output current of 2 A, isolation voltage of 5000 Vrms, and rise/fall times of 75 ns/55 ns. The device operates within a temperature range of -40°C to +100°C, with a forward voltage of 1.43 V at 25 mA input.

Isolators - Gate Drivers Feature Summary

• High common-mode transient immunity for noise-resistant operation
• Integrated bootstrap diode capability for half-bridge applications
• Low propagation delay and pulse width distortion

Isolators - Gate Drivers Applications

• IGBT and MOSFET gate driving
• Industrial power supplies
• Inverter circuits

Isolators - Gate Drivers Procurement Notes

Verify the manufacturer designation as onsemi, which acquired Fairchild's semiconductor business. Confirm the specific suffix 'SD' denotes the tape-and-reel packaging variant. Ensure compliance with RoHS directives and check for any recent product change notices regarding pinout or material composition updates.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching and robust isolation are required for power electronics. The 2A peak drive current supports direct driving of medium-power MOSFETs and IGBTs without external buffers. Consider the 5000 Vrms isolation rating for safety-critical industrial environments.

Isolators - Gate Drivers Part Context

This part belongs to the FOD3180 series of high-speed optocouplers designed for gate drive applications. It serves as a bridge between low-voltage control logic and high-voltage power stages, providing galvanic isolation while maintaining signal integrity at high frequencies.

Isolators - Gate Drivers Replacement Considerations

Check for equivalents such as the FOD3180T or FOD3182 variants depending on packaging requirements and specific current drive needs. Verify pin compatibility before substitution.
