Overview
The TIL197BX is a single-channel Darlington output optocoupler manufactured by Isocom Components. It features a plastic DIP-4 package with four through-hole pins. The device provides high isolation voltage of 5300Vrms and supports AC input current up to 50mA. Typical rise and fall times are 100μs, with a maximum forward voltage of 1.4V. Operating temperature ranges from -55°C to 100°C. Current transfer ratio varies between 500% minimum and 7500% maximum. UL recognition is included.
Feature Summary
- Darlington transistor output configuration for high gain
- AC input capability for direct line sensing
- High isolation voltage rating for safety
- UL recognized certification
Applications
- Industrial control systems
- Power supply feedback loops
- Solid-state relay drivers
- Microprocessor interface circuits
Procurement Notes
Verify the specific suffix BX against official Isocom documentation to confirm exact binning or testing criteria. Confirm RoHS compliance status as datasheets may vary by production batch. Check lead times due to potential availability constraints. Ensure DIP-4 pin compatibility with target PCB footprint. Validate operating temperature range requirements against application environment specifications.
Selection Notes
Select this component when high current transfer ratio is required without external amplification. Suitable for applications needing AC input detection directly from the LED side. Consider thermal management within the specified -55°C to 100°C range. Compare switching speed limitations against system timing requirements due to Darlington output characteristics.
Part Context
Part of the TIL197 series offering Darlington output optocouplers. Designed for general-purpose isolation tasks requiring high sensitivity. Manufactured in Thailand. Available in standard DIP-4 plastic packaging. Complements other Isocom optocoupler families for diverse isolation needs.
Replacement Considerations
TIL197BX serves as a variant within the TIL197 family. Verify pinout and electrical parameters against direct replacements like TIL197. Ensure isolation voltage and current transfer ratio meet or exceed original design requirements. Check package dimensions for mechanical compatibility.
