Procurement Notes

Verify the specific suffix (B0G) against official Taiwan Semiconductor documentation to confirm package type and tape/reel specifications. Ensure the selected variant matches the required voltage tolerance and operating temperature range for your design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the automotive qualification status applies to the exact part number ordered.

Selection Notes

Select this component when a low-voltage adjustable reference is needed for 3.3 V systems. It serves as a lower voltage alternative to TL431 devices. Consider the 1% or 0.5% precision variants if tight voltage regulation is required. Verify compatibility with optocoupler driving requirements due to its suitability for such applications. Check thermal performance against the 100 ppm/°C temperature coefficient specification.

Part Context

The TS431 series comprises monolithic IC voltage references functioning as programmable shunt regulators. These devices are designed for low-temperature drift applications. The TS431ACT B0G represents a specific configuration within this family, offering enhanced performance over standard TL431 counterparts in low-voltage scenarios. It is part of Taiwan Semiconductor's portfolio of power management integrated circuits.

Replacement Considerations

Public confirmed substitute part numbers include TS431ACT A3G and TS431BCT B0G. Compare pinout and electrical parameters before substitution. Ensure the replacement maintains the required voltage precision and operating current range. Verify package compatibility if mechanical constraints exist.
