Overview
The TLP525G-2(F) is a dual-channel triac output optoisolator manufactured by Toshiba Semiconductor and Storage. It integrates two photo-triacs optically coupled to gallium arsenide infrared emitting diodes within an eight-lead plastic DIP package. The device provides electrical isolation with a maximum continuous output current of 80 mA and supports a maximum input current of 50 mA. It operates reliably across a temperature range of -40°C to 100°C and features a 2500Vrms isolation voltage rating, ensuring robust signal transmission between isolated circuits.
Feature Summary
- Dual isolated channels integrated in a single eight-lead plastic DIP package
- Photo-triac output optically coupled to gallium arsenide infrared emitting diode
- High isolation voltage rating of 2500Vrms for safe circuit separation
Applications
- Industrial control systems requiring isolated switching
- Solid-state relay driver circuits
- AC load switching applications
Procurement Notes
Verify the specific ordering suffix (F) against the manufacturer's official documentation to confirm tape-and-reel packaging specifications if applicable. Ensure the component matches the required lead form and package dimensions specified in the datasheet. Cross-reference the isolation voltage and current ratings with system requirements before procurement to guarantee compatibility.
Selection Notes
Select this component when dual-channel isolation is required within a compact DIP footprint. The 80 mA output current capability suits moderate AC load switching tasks. Consider the operating temperature range and isolation voltage limits relative to the target application environment. Verify that the gallium arsenide LED input characteristics align with the driving circuit logic levels.
Part Context
This part belongs to the TLP525G series, which includes variants with different channel counts such as the single-channel TLP525G and the four-channel TLP525G-4. All variants share the same core technology involving photo-triac outputs coupled to infrared LEDs. The series is designed for general-purpose isolation applications where reliable switching and high isolation performance are necessary.
Replacement Considerations
Direct substitutes include other dual-channel triac optoisolators in 8-DIP packages from manufacturers like ON Semiconductor or Vishay. Verify pinout compatibility, isolation voltage ratings, and current transfer ratios before substitution. Ensure the replacement part meets the same thermal and electrical specifications defined in the original datasheet.
