1N5532D-1

Overview

The Microchip Technology 1N5532D-1 is a single Zener diode with a nominal voltage of 12 V and a maximum power dissipation of 500 mW. It features a tight tolerance of ±1% and operates within a temperature range of -65°C to +175°C TJ. The device utilizes a DO-204AH (DO-35) axial through-hole package, exhibits a maximum impedance of 90 Ohms at the test current, and maintains a reverse leakage current of 50 nA at 10.8 V.

Feature Summary

• Provides high-precision voltage regulation with ±1% tolerance for sensitive circuit applications.
• Features low reverse leakage characteristics suitable for stable reference designs.
• Constructed with double plug metallurgically bonded technology for enhanced reliability.

Applications

• Precision voltage reference circuits
• Overvoltage protection in sensitive electronics
• Low noise analog signal conditioning

Procurement Notes

Verify the specific suffix designation when ordering, as it indicates manufacturing lot or packaging variations that do not alter electrical function. Confirm compliance requirements such as RoHS status against project specifications. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability throughout the supply chain.

Selection Notes

Select this component when strict voltage accuracy is required due to its ±1% tolerance compared to standard variants. The wide operating temperature range supports deployment in harsh industrial environments. Verify that the through-hole DO-35 package aligns with the target PCB layout constraints and assembly processes before finalizing the design.

Part Context

This part belongs to the 1N5518B-1N5546B-1 Low Noise Zener Diode Series manufactured by Microchip Technology. The series is characterized by low noise performance and is available in various tolerance grades. The 'D' suffix specifically denotes the tighter ±1% voltage tolerance variant within this product family.

Replacement Considerations

The 1N5532D is a parameter-equivalent alternative. Other variants like 1N5532C offer different tolerance levels but share the same core electrical profile.
