1N5227BE3

Single Zener Diodes Overview

The Microchip Technology 1N5227BE3 is a single Zener diode housed in a DO-35 glass axial leaded package. It provides a nominal Zener voltage of 3.6 V with a tolerance of ±5%. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 15 µA, a Zener impedance of 24 Ohms, and a forward voltage of 1.5 V at 200 mA. The component is RoHS compliant.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-leaded construction for robust environmental protection
• Wide operating temperature range suitable for demanding industrial conditions
• Standardized 5% voltage tolerance for consistent regulation performance

Single Zener Diodes Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Overvoltage protection stages in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' confirms RoHS compliance and lead-free status as distinct from non-compliant variants. Confirm the package type matches the required DO-35 footprint. Ensure the 3.6 V rating aligns with circuit design requirements before integration.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, glass-encapsulated Zener diode is required for high-reliability applications. The DO-35 package offers through-hole mounting compatibility. Consider the 500 mW power rating and 3.6 V nominal voltage against specific circuit load and thermal constraints.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators manufactured by Microchip Technology. The series covers a wide voltage selection from 2.4 V to 200 V in standard packages. The BE3 suffix indicates environmental compliance and specific manufacturing screening levels.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include 1N5227B, though verification of RoHS compliance and hermetic sealing differences is necessary. Cross-manufacturer equivalents must match the 3.6 V Zener voltage, 500 mW power dissipation, and DO-35 package dimensions.
