TLP525G(TP5,F)

Overview

The TLP525G(TP5,F) is a single-channel photocoupler optoisolator manufactured by Toshiba Semiconductor and Storage. It features a triac output designed for high-voltage isolation applications, providing an isolation voltage of 2500Vrms. The device operates with a maximum off-state voltage of 400 V and requires a trigger current of up to 10 mA for activation. Packaged in a standard 4-DIP (0.300 inch or 7.62 mm) configuration, it utilizes through-hole mounting technology. This component lacks zero-crossing circuitry, making it suitable for phase control applications where precise timing relative to the AC waveform zero point is not required.

Feature Summary

• Provides galvanic isolation between input and output circuits using optical transmission
• Features a triac output stage capable of controlling AC loads directly
• Designed for robust high-voltage isolation performance in industrial environments

Applications

• AC motor speed control systems
• Solid-state relay driver circuits
• Industrial process control isolation interfaces

Procurement Notes

Verify the specific suffix TP5 against the manufacturer's official datasheet to confirm package variant and tape-and-reel specifications. Ensure the ordering part number matches the exact isolation rating and output type requirements for the target design. Cross-reference the manufacturer's latest documentation to confirm compliance with current environmental standards and availability status before finalizing procurement orders.

Selection Notes

Select this component when a single-channel triac output is required for AC load switching without zero-crossing detection. Consider the 2500Vrms isolation rating for safety-critical applications. Evaluate the 400V off-state voltage capability against the peak line voltage of the application. Confirm that the DIP-4 package fits the PCB layout constraints and that the 10mA trigger current aligns with the driving logic level capabilities.

Part Context

The TLP525G series belongs to Toshiba's family of photo-triac outputs designed for general-purpose AC switching. Variants such as TLP525G-2(F) offer dual channels, while TLP525G-4(F) provides four isolated channels in larger packages. The TLP525G(TP5,F) represents the single-channel version in a compact DIP-4 footprint, serving as a fundamental building block for basic opto-isolated AC control circuits.

Replacement Considerations

Direct substitutes include other single-channel photo-triac optocouplers with comparable 2500Vrms isolation and similar pinout configurations. Verify that alternative components match the 400V off-state voltage and trigger current specifications. Check for equivalent DIP-4 packaging to ensure mechanical compatibility during replacement.
