1. Applications
• Industrial Inverters • MOSFET Gate Drivers • IGBT Gate Drivers • Induction Cooktop and Home Appliances
2. General
The TLP351H is a photocoupler in a DIP8 package that consists of a GaAℓAs infrared light-emitting diode (LED) optically coupled to an integrated high-gain, high-speed photodetector IC chip. It provides guaranteed performance and specifications at temperatures up to 125.The TLP351H has an internal Faraday shield that provides a guaranteed Common-mode transient immunity of ±20 kV/µs. It has a totem-pole output that can both sink and source current. The TLP351H is ideal for IGBT and power MOSFET gate drive.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
