FOD8343R2
Description
Technical Parameters
The FOD8343R2 optocoupler gate driver is a high-performance solution catering to medium-power IGBT/MOSFET applications. Noteworthy features include an 8 mm creepage and clearance distance, 0.4 mm insulation distance, and a robust 4.0 A maximum peak output current. The utilization of P-Channel MOSFETs enables a voltage swing close to the supply rail, while the device maintains a minimum common mode rejection of 50 kV/s across a wide supply voltage range (10 V to 30 V). With fast switching speeds, including a maximum propagation delay of 210 ns and under-voltage lockout with hysteresis, the FOD8343R2 ensures precise control. Operating in an extended industrial temperature range (-40°C to 100°C) and meeting safety standards such as UL1577 and DIN EN/IEC60747-5-5, this gate driver is a reliable and compliant choice for industrial systems demanding high voltage insulation, efficiency, and regulatory adherence.

Description:
The FOD8343 series is a 4.0 A maximum peak output current gate drive optocoupler, capable of driving medium−power IGBT / MOSFETs. It is ideally suited for fast−switching driving of power IGBT and MOSFET used in motor−control inverter applications, and high−performance power systems. The FOD8343 series utilizes stretched body package to achieve 8 mm creepage and clearance distances (FOD8343T), and optimized IC design to achieve reliably high−insulation voltage and high−noise immunity. The FOD8343 series consists of an Aluminum Gallium Arsenide (AlGaAs) Light−Emitting Diode (LED) optically coupled to an integrated circuit with a high−speed driver for push−pull MOSFET output stage. The device is housed in a stretched body, 6−pin, small outline, plastic package.
