Toshiba TLP579xH Gate Driver Photocoupler

Toshiba’s TLP579xH family of three gate driver photocouplers offer isolated control for 1A to 6A gate currents, ideal for driving MOSFETs and IGBTs in industrial and renewable energy systems.

Featuring rail-to-rail and non-rail-to-rail output and stable propagation delay across -40°C to +125°C, they ensure reliable switching in harsh environments.
Enhanced optical coupling boosts efficiency, while UVLO protection secures performance at low voltages.

Housed in compact SO6L packages with 5000Vrms isolation and 8mm creepage, they support flexible PCB layout and meet stringent safety standards—perfect for SiC-based designs in PV inverters, UPSs, and EV charger.
