TLP525GF

Triac, SCR Output Optoisolators Overview

The TLP525GF is a single-channel optoisolator manufactured by Toshiba Semiconductor and Storage. It features a GaAs infrared LED coupled with a photo-triac output device, housed in a standard 4-DIP package with a 7.62mm (0.300-inch) width. The component provides an isolation voltage of 2500Vrms between the input and output circuits. Key electrical parameters include a maximum DC forward current of 50mA for the input side and a typical forward voltage of 1.15V. The device is designed to operate within a temperature range of -40°C to 100°C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'G' against the official Toshiba datasheet to confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the selected variant matches the required DIP package dimensions and pin configuration for PCB layout compatibility. Cross-reference the manufacturer's latest documentation to confirm availability and any potential design-in recommendations or obsolescence notices prior to final procurement decisions.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a triac output is required for AC load control rather than a simple phototransistor. Consider the 2500Vrms isolation rating for safety-critical interfaces. Evaluate the operating temperature range to ensure suitability for the intended environmental conditions. Confirm that the zero-crossing capability is not needed, as this specific model lacks that feature, distinguishing it from other variants in the series.

Triac, SCR Output Optoisolators Part Context

This part belongs to the TLP525 series of optoisolators from Toshiba Semiconductor and Storage. The series typically includes various output configurations such as phototransistors and triacs. The TLP525GF specifically denotes the triac output version within a 4-pin DIP package. This family is commonly used in general-purpose isolation applications where compact size and reliable performance are prioritized.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include other Toshiba TLP525 series variants with triac outputs, such as TLP525-1 or TLP525-2, provided they match the package and electrical characteristics. Verify equivalent isolation voltage and output current ratings before substitution. Consult the manufacturer's cross-reference guide for approved replacements to ensure functional compatibility.

Triac, SCR Output Optoisolators FAQ
