Overview
The TLP525G(FUJT,F) is a single-channel optocoupler featuring a Gallium Arsenide infrared LED input and a photo-triac output. It provides an isolation voltage of 2500 Vrms, ensuring robust electrical separation between control and load circuits. The device operates with a forward current up to 60 mA and supports peak repetitive forward current of 1 A. It exhibits a high collector-emitter breakdown voltage of 400 V and a low on-state current of 10 mA. The component is housed in a compact 4-DIP package, suitable for surface or through-hole mounting.
Feature Summary
- Integrates a GaAs infrared emitting diode with a photo-triac detector for efficient optical coupling
- Provides reinforced insulation with a 2500 Vrms isolation rating for safety-critical applications
- Features a triac output capable of directly switching AC loads without external bridge rectifiers
Applications
- Solid-state relays for AC load switching
- Industrial motor control interfaces
- Power supply feedback loops
Procurement Notes
Verify the specific suffix FUJT against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and binning codes. Ensure that the procurement source provides traceability documentation matching Toshiba Semiconductor and Storage manufacturing records. Cross-reference the date code and lot number with authorized distributor records to prevent counterfeit components. Confirm that the device meets RoHS compliance standards as defined in the latest product release notes.
Selection Notes
Select this component when direct AC switching capability is required within a single channel. The photo-triac output eliminates the need for additional rectification circuitry compared to phototransistor alternatives. Consider the 2500 Vrms isolation rating for applications requiring strict galvanic separation. Evaluate the 4-DIP package dimensions against PCB layout constraints before finalizing the design.
Part Context
This part belongs to the TLP525G family of photocouplers, which includes variants with different channel counts and package types. The TLP525G-2 offers dual channels in an 8-DIP package, while the TLP525G-4 provides four channels in a 16-DIP configuration. All variants share the same core technology but differ in pinout and isolation channel density.
Replacement Considerations
Direct substitutes include other single-channel photo-triac optocouplers with comparable 2500 Vrms isolation ratings. Verify pin compatibility and on-state current requirements when considering alternatives from other manufacturers.
