TLP250(D4-LF1,F)

Isolators - Gate Drivers Overview

The TLP250(D4-LF1,F) is an 8-pin DIP photocoppler gate driver manufactured by Toshiba Semiconductor and Storage. It integrates an aluminum gallium arsenide light-emitting diode with an integrated optical detector to provide electrical isolation for power switching applications. The device features a push-pull output stage capable of driving IGBTs and power MOSFETs directly. Key electrical parameters include a maximum input current of 5mA, a supply voltage range of 10V to 35V, and a peak output current of ±1.5A. The isolation voltage is rated at a minimum of 2500Vrms, with a maximum operating isolation voltage of 890Vpk and a withstand voltage of 4000Vpk.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix (D4-LF1,F) against the manufacturer's current datasheet to confirm compliance with RoHS directives and VDE certification standards. Confirm package type and pinout compatibility before integration. Note that availability status may vary as this component has been marked obsolete in some distributor channels; check for active manufacturing status or approved substitutes.

Isolators - Gate Drivers Selection Notes

Select this component when designing circuits requiring galvanic isolation between control logic and high-power switching devices. Ensure the supply voltage remains within the 10V to 35V range and that the load current does not exceed the ±1.5A output capability. Verify that the required isolation voltage meets the system's safety requirements, specifically checking against the 2500Vrms minimum rating.

Isolators - Gate Drivers Part Context

This part belongs to the TLP250 series of photocouplers designed for gate driving applications. It is distinct from variants like the TLP250H which offer higher speed and different packaging options. The D4-LF1,F suffix indicates specific certification and lead-free compliance attributes defined by Toshiba Semiconductor and Storage for this particular iteration of the standard TLP250 device.

Isolators - Gate Drivers Replacement Considerations

Public sources indicate the TLP250(D4-LF1,F) is obsolete. Potential substitutes include similar gate driver photocouplers from Toshiba such as the TLP257 or TLP350 series, provided they match the DIP-8 package and electrical specifications. Always verify pinout and isolation ratings before substitution.
