TLP250 / TLP250H / TLP250S — Optocoupler Gate Driver IC
The TLP250, TLP250H, and TLP250S are high-speed optocoupler gate driver ICs from Toshiba, widely used to drive IGBTs and power MOSFETs with full galvanic isolation. All variants offer fast propagation delay and wide supply voltage range, making them the go-to isolated gate drivers for inverters, motor drives, and switching power supplies.
