ZR431CL

Overview

The ZR431CL is a three-terminal adjustable shunt voltage reference manufactured by Diodes Incorporated. It operates within an input voltage range of 2.5V to 20V and provides an initial accuracy of ±2%. The device features a temperature coefficient of 50 PPM/°C and supports a maximum shunt current of 100 mA. It is designed for through-hole mounting in a TO-92-3 package, with an operating temperature range spanning from -40°C to +85°C.

Feature Summary

• Provides adjustable precision shunt regulation with output control capabilities
• Offers excellent temperature stability across the specified operating range
• Supports high output current handling capability up to 100 mA

Applications

• Voltage regulation in power supply circuits
• Reference voltage sources for analog-to-digital converters
• Battery charging management systems

Procurement Notes

Verify component authenticity against Diodes Incorporated specifications due to potential availability variations. Confirm package integrity and pinout alignment with TO-92-3 standards. Ensure environmental compliance requirements match project constraints. Validate electrical parameters against datasheet limits before integration into final designs.

Selection Notes

Select this component when adjustable shunt regulation with ±2% accuracy is required. Consider the 100 mA current capacity for load driving needs. Evaluate thermal performance within the -40°C to +85°C range. Compare against fixed reference alternatives if adjustability is not essential for the specific application design.

Part Context

This part belongs to the ZR431 family of adjustable precision Zener shunt regulators. It shares functional similarities with other Diodes Incorporated voltage references but offers specific through-hole packaging and current handling characteristics distinct from surface-mount variants in the same product line.

Replacement Considerations

ZR431LC02L is a documented substitute option.
