TLP525G(LF1,F)

Overview

The TLP525G(LF1,F) is a single-channel photo-triac optocoupler manufactured by Toshiba Semiconductor and Storage. It features an isolation voltage of 2500Vrms and a maximum trigger current of 10mA. The device supports an RMS on-state current of 100mA and operates within a temperature range of -40°C to 100°C. Packaged in a 4-DIP configuration, it provides electrical isolation for AC control applications.

Feature Summary

• Single-channel photo-triac output for isolated AC switching
• High isolation voltage rating of 2500Vrms
• Suitable for zero-crossing detection and AC interface circuits

Applications

• Isolated AC control systems
• Solid-state relay interfaces
• Zero-voltage switching circuits

Procurement Notes

Verify component authenticity through authorized distributors as the part may be obsolete. Confirm package integrity and lead condition upon receipt. Cross-reference datasheet specifications with application requirements to ensure compatibility with system voltage and current ratings before integration.

Selection Notes

Select this component for applications requiring galvanic isolation between low-power control logic and high-voltage AC loads. Ensure the load current does not exceed the 100mA RMS rating. Consider thermal management if operating near the upper temperature limit of 100°C.

Part Context

This model belongs to Toshiba's phototriac coupler family designed for industrial and consumer AC power control. It replaces older discrete triac-driver solutions by integrating the LED and triac in a compact DIP-4 package, simplifying PCB layout and reducing component count in isolation barriers.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify end-of-life status with the manufacturer for long-term supply chain planning.
