TLP754F(D4-TP4,F)

Overview

The TLP754F(D4-TP4,F) is a photocoupler in an 8-SMD package, consisting of a GaAlAs infrared LED optically coupled to an integrated high-gain, high-speed photodetector IC chip. It provides guaranteed performance up to 125°C with an internal noise shield ensuring ±20 kV/µs common mode transient immunity. Key electrical parameters include a minimum isolation voltage of 5000 Vrms, a maximum threshold input current of 5.0 mA, and a maximum supply current of 1.3 mA. Propagation delay times are specified as tpHL = 400 ns (max) and tpLH = 550 ns (max), with pulse width distortion limited to 400 ns (max).

Procurement Notes

Verify the specific suffix D4-TP4-F against official Toshiba documentation to confirm VDE approval status and safety standard compliance. Ensure the component matches the required DIP8 or SMD footprint variant. Confirm RoHS compliance and operating temperature range (-40 to 125°C) requirements for your specific design environment before procurement.

Selection Notes

Select this component when high-speed digital isolation is required between control circuits and power stages. The open-collector output requires appropriate pull-up resistor selection based on the target logic voltage level. Consider the 5000 Vrms isolation rating for applications demanding robust galvanic separation between low-voltage control and high-voltage power domains.
