1N5524B

Overview

The Microchip Technology 1N5524B is a low voltage avalanche Zener diode rated at 0.5 W with a nominal breakdown voltage of 5.6 V measured at a test current of 3.0 mA. It features a ±5% voltage tolerance and is housed in a hermetically sealed axial-lead glass DO-35 (DO-204AH) package. The device operates within a junction temperature range of -65°C to +175°C, supports a maximum DC regulator current of 3.5 mA, and exhibits a maximum reverse leakage current of 3.0 µA at 3.0 V.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Offers minimal capacitance characteristics suitable for high-frequency applications
• Demonstrates inherent radiation hardness capabilities

Applications

• Voltage regulation circuits requiring stable reference levels
• Overvoltage protection systems
• Clamping applications in electronic signal paths

Procurement Notes

Verify the specific suffix requirements against the datasheet nomenclature to ensure correct tolerance and qualification levels. Confirm RoHS compliance status if required, as it applies only to commercial grade versions. Check for metallurgical bond options if military qualifications are necessary. Ensure ordering specifications match the desired JEDEC type number and packaging format.

Selection Notes

Select this component when a 5.6 V Zener reference with ±5% tolerance is required in an axial-lead package. Consider the thermal resistance values for derating calculations based on ambient conditions. Evaluate the noise density specifications if low-noise performance is critical for the application environment.
