TS431BCT B0G

Overview

The TS431BCT B0G is a low-voltage, three-terminal adjustable shunt voltage reference manufactured by Taiwan Semiconductor Corporation. It operates within a cathode current range of 60 µA to 30 mA and provides an output voltage adjustable between 1.24 V and 6 V using external resistors. The device features a typical temperature coefficient of 100 ppm/°C and maintains an initial accuracy of 0.5%. Designed for through-hole mounting in TO-92 packages, it supports operation temperatures from -40°C to +125°C.

Feature Summary

• Adjustable output voltage capability between 1.24 V and 6 V via external resistor divider
• Low minimum operating cathode current enabling efficient power management
• High precision with 0.5% initial accuracy tolerance
• Wide operating temperature range suitable for demanding environments

Applications

• Regulating 3.3 V switching power supplies
• Driving optocouplers in feedback loops
• Portable equipment requiring low-power references
• Battery-powered systems needing precise voltage monitoring

Procurement Notes

Verify the specific suffix B0G against official datasheets to confirm package type and tolerance. Confirm RoHS compliance status as required by project specifications. Check component lifecycle status to ensure availability for long-term production needs. Validate that the through-hole TO-92 package matches the target PCB footprint requirements.

Selection Notes

Select this component when a low-voltage adjustable reference is needed below the standard 2.5 V threshold. It is ideal for applications where minimizing quiescent current is critical. Consider the TO-92 package constraints if surface-mount space is limited. Ensure the 6 V maximum output aligns with the system's reference voltage requirements.

Part Context

This part belongs to the TS431 series of low-voltage shunt voltage references. It serves as a specialized alternative to traditional TL431 devices, offering lower minimum operating currents and voltages. The series is widely used in compact power supply designs and battery-operated electronics where space and efficiency are prioritized over high-voltage handling capabilities.

Replacement Considerations

Direct replacements include the TS431BIYLT for surface-mount SOT-23-5 applications. Verify pinout compatibility before substituting with other adjustable shunt references. Ensure replacement parts maintain the same 0.5% accuracy and 100 ppm/°C temperature coefficient.
