The TLP250H(F) from Toshiba is a high-performance photocoupler gate driver designed for driving IGBTs and power MOSFETs in isolated power control applications. It integrates a photo-IC input/output isolation structure with a totem-pole output stage, allowing it to source and sink high gate-drive current for efficient switching control.
The device provides a maximum peak output current of ±2.5A and operates from a recommended supply voltage range of 10V to 30V. Its high output drive capability makes it suitable for directly driving the gates of many power semiconductor devices used in inverter and switching power circuits.
TLP250H(F) provides an isolation voltage of 3750Vrms and a common-mode transient immunity of ±40kV/μs, helping maintain stable operation in electrically noisy high-voltage environments. The maximum propagation delay is 500ns, while pulse-width distortion is specified at 50ns.
The device supports an operating temperature range of -40°C to +125°C and is supplied in an 8-pin DIP package. Typical applications include industrial inverters, air-conditioner inverters, induction heating equipment, photovoltaic inverters, motor drives, UPS systems, and isolated IGBT or MOSFET gate-drive circuits.
