TL431BCLPRAG

Overview

The TL431BCLPRAG is an adjustable shunt voltage reference IC manufactured by onsemi, housed in a TO-92-3 (TO-226) through-hole package. It features an initial accuracy of ±0.4% and operates within a temperature range of -40°C to +85°C. The device supports an input voltage up to 36 V with a maximum cathode current of 100 mA. It provides a minimum output voltage of 2.495 V and includes a standard temperature coefficient of 50 ppm/°C. This component is classified as obsolete.

Feature Summary

• Provides precise adjustable voltage referencing via shunt regulation architecture
• Ensures high initial accuracy with ±0.4% tolerance for stable reference performance
• Operates reliably across extended industrial temperature ranges from -40°C to +85°C

Applications

• Precision power supply feedback loops
• Voltage monitoring circuits
• Comparator references

Procurement Notes

This component is officially designated as obsolete by the manufacturer. Availability is restricted to remaining stock or secondary market sources. Verify RoHS compliance status and specific manufacturing lot dates when sourcing replacements. Ensure that any substitute components match the required thermal and electrical specifications for your application design.

Selection Notes

Select this part for applications requiring high precision voltage referencing in through-hole designs. The ±0.4% accuracy suits tight tolerance requirements compared to standard variants. Consider the extended temperature range for industrial environments. Due to its obsolete status, evaluate long-term supply chain risks and identify qualified alternative components early in the design phase.

Part Context

Part of the TL431 family of programmable shunt regulators. These devices function as low-cost alternatives to Zener diodes, offering superior performance in terms of temperature stability and dynamic impedance. The TL431 series is widely used in switching power supplies and linear regulators for error amplification and voltage reference generation.
