TS432BCT A3G

Overview

The TS432BCT A3G is an adjustable shunt voltage reference manufactured by Taiwan Semiconductor Corporation. It provides a stable reference voltage ranging from 1.24 V to 18 V with an initial accuracy of 0.5%. The device operates within a temperature range of 0°C to +70°C and features a maximum series input voltage of 18 V. It supports a maximum cathode current of 100 mA and exhibits a temperature coefficient of 50 ppm/°C. The component is housed in a TO-92-3 through-hole package.

Feature Summary

• Provides adjustable precision shunt reference functionality
• Ensures high initial accuracy for stable voltage regulation
• Supports wide operating voltage ranges up to 18 V

Applications

• Precision voltage references in power supply circuits
• Voltage monitoring and threshold detection systems
• Battery-operated equipment requiring stable reference voltages

Procurement Notes

Verify the specific suffix 'A3G' against official Taiwan Semiconductor documentation, as standard listings often cite 'A3'. Confirm RoHS compliance status and ensure the TO-92-3 package matches design requirements. Check for obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a low-cost, through-hole adjustable reference is required. Ensure the 100 mA cathode current capability meets load demands. Verify that the 50 ppm/°C temperature coefficient satisfies thermal stability needs for the target application environment.

Part Context

This part belongs to the TS432 family of programmable shunt regulators. It serves as a cost-effective alternative to fixed voltage references, offering flexibility in circuit design. The TO-92 package makes it suitable for general-purpose electronics where space constraints are less critical than in surface-mount applications.

Replacement Considerations

Direct substitutes include other adjustable shunt references like the TL431 series. Verify pinout compatibility and electrical specifications such as cathode current limits and temperature coefficients before substitution.
