TLP351H(TP1,F)

Isolators - Gate Drivers Overview

The TLP351H(TP1,F) is a high-speed logic output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a GaAlAs light-emitting diode with an integrated photodetector in an 8-pin surface-mount package. The device provides electrical isolation of 3750 Vrms and supports a supply voltage range of 10V to 30V. Key electrical parameters include a maximum forward current of 20 mA, a typical forward voltage of 1.55 V, and a peak output current capability of 400 mA for both sourcing and sinking. Propagation delays are limited to 700 ns, with a pulse width distortion of 500 ns maximum. It operates within a temperature range of -40°C to 125°C.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix (TP1,F) confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-SMD gull-wing package dimensions match the target PCB footprint. Ensure the component meets the required insulation coordination standards for the intended isolation barrier application before finalizing procurement specifications.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching and robust noise immunity are critical for gate drive applications. The 20 kV/µs CMTI rating distinguishes it from standard optocouplers in noisy power electronics environments. Consider the 400 mA output current capability against the load requirements of the target transistor or IGBT gate. Verify compatibility with the system's supply voltage range of 10V to 30V.
