TLP351H(F)

Isolators - Gate Drivers Overview

The TLP351H(F) is a single-channel optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates a GaAlAs light-emitting diode with an integrated photodetector in an 8-lead DIP package. The device provides high-speed switching capabilities with rise and fall times of 50 ns and a maximum propagation delay of 700 ns. It supports a collector supply voltage range of 10 V to 30 V and delivers an output current of 600 mA. Key electrical specifications include a forward voltage of 1.55 V, a maximum forward current of 20 mA, and a power dissipation of 260 mW. The unit offers an isolation voltage of 3750 Vrms and operates within a temperature range of -40 °C to +125 °C.

• Induction cooktops and home appliances

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix (F) indicates tube packaging when ordering through distributors. Confirm RoHS compliance status via the manufacturer's latest documentation. Ensure the DIP-8 package dimensions match the target PCB footprint. Check for any SVHC declarations required by regional regulations. Validate that the 3750 Vrms isolation rating meets the safety standards of the end application.

Isolators - Gate Drivers Selection Notes

Select this component when a dedicated gate driver with optical isolation is required for medium-power switching applications. The 600 mA output current is suitable for driving standard IGBTs and MOSFETs without external buffers. Consider the 50 ns switching speed for applications requiring moderate frequency operation. The wide temperature range makes it appropriate for industrial environments where thermal stability is critical.

Isolators - Gate Drivers Part Context

The TLP351H(F) belongs to Toshiba's family of optocoupler gate drivers designed for power electronics. It replaces older discrete driver solutions by integrating the LED and photodetector with a push-pull output stage. This integration reduces board space and simplifies design compared to using separate optocouplers and driver ICs. The device is part of the broader TLP351 series, which includes variations like the TLP351H(TP1,F) in SMD packages.
