1N5234B-1E3

Single Zener Diodes Overview

The Microchip Technology 1N5234B-1E3 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.1 V with a tolerance of 5%. The device operates in a DO-7 axial through-hole package and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 3 µA, a Zener impedance of 8 Ohms at a test current of 20 mA, and a forward voltage of 1.1 V. The component supports an operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single unidirectional Zener junction
• Features hermetically sealed glass construction for environmental protection
• Supports high-temperature operation suitable for demanding industrial environments

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications for transient suppression

Single Zener Diodes Procurement Notes

Verify the specific suffix '1E3' indicates lead-free compliance when sourcing. Confirm that the DO-7 package matches the target PCB footprint requirements. Ensure the 5% voltage tolerance aligns with circuit design specifications. Check for any military or aerospace screening options if required by the application standard.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V regulation point is needed in a through-hole configuration. Consider the 500 mW power dissipation limit relative to expected current loads. Evaluate the 8 Ohm impedance against noise sensitivity requirements. Compare the -65°C to +200°C range against ambient conditions.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N52xxB series of Zener diodes manufactured by Microchip Technology. It serves as a surface-mount equivalent alternative to older glass-encapsulated variants while maintaining similar electrical performance profiles. The series covers a wide voltage range from 2.4 V to 200 V.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5234B without the E3 suffix for non-lead-free versions. Surface mount alternatives like the MSP1N5234AUR-1E3 offer the same electrical parameters in a MELF package.
