Technical Specifications

The TLP351H(D4 features a minimum isolation voltage of 5000 Vrms. The typical turn-on and turn-off times are very short, contributing to efficient switching. It requires a low input current to operate, reducing the load on the control circuit. The operating temperature range is typically -40°C to +100°C. The package type is SO6. The output voltage is dependent on the configuration and external circuitry. The device provides excellent common-mode transient immunity, preventing false triggering.

This MOSFET/IGBT driver uses a GaAlAs infrared light-emitting diode (LED) on the input side and a photovoltaic generator array on the output side. The LED converts electrical energy into light, which then generates voltage in the photovoltaic array, driving the gate of the MOSFET or IGBT. This mechanism provides excellent electrical isolation and enables high-speed switching.

The TLP351H(D4) is a crucial component in applications where electrical isolation is paramount for safety and reliable operation. Its fast switching speed and low power consumption make it an ideal choice for modern power electronics designs.
