1N5231CTR

Single Zener Diodes Overview

The Fairchild Semiconductor 1N5231CTR is a single-channel general-purpose Zener diode with a nominal voltage of 5.1 V and a maximum power dissipation of 500 mW. It features a tight tolerance of ±2% and operates within a temperature range of -65°C to 200°C. The device utilizes an SOD-27 through-hole package with two pins, offering a maximum dynamic impedance of 17 Ω at a test current of 20 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with high precision due to a narrow ±2% tolerance band.
• Capable of handling significant thermal loads up to 200°C junction temperature.
• Designed for reliable operation in extreme cold environments down to -65°C.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Over-voltage protection stages
• Clamping applications in signal conditioning

Single Zener Diodes Procurement Notes

Verify the specific suffix CTR against official datasheets to confirm packaging details and availability status. Ensure the component meets RoHS compliance requirements if mandated by project specifications. Cross-reference manufacturer part numbers to avoid confusion with similar variants like 1N5231B or 1N5231C.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is required compared to standard 5% tolerance devices. The SOD-27 axial leaded form factor suits manual assembly or specific board layouts requiring through-hole mounting. Evaluate thermal management needs given the 500 mW dissipation rating.

Single Zener Diodes Part Context

This part belongs to the widely used 1N52xx series of Zener diodes, known for their reliability in discrete semiconductor applications. Manufactured originally by Fairchild Semiconductor, now part of onsemi, these components are standard choices for basic voltage regulation tasks in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Equivalent parts include onsemi 1N5231B (±5% tolerance) or 1N5231C (±2% tolerance). Verify pinout compatibility and ensure replacement packages match the SOD-27/DO-35 axial specification.
