1N5235B-T

Single Zener Diodes Overview

The Diodes Incorporated 1N5235B-T is a discontinued 500mW epitaxial Zener diode housed in a DO-35 glass axial-lead package. It provides a nominal Zener voltage of 6.8V with a ±5% tolerance, tested at 20mA. The device features a maximum Zener impedance of 5Ω and a reverse leakage current of 3µA at 5V. Operating temperatures range from -65°C to +175°C. The suffix '-T' indicates tape and reel packaging.

Single Zener Diodes Feature Summary

• Hermetically sealed glass compression bonded construction
• High stability epitaxial Zener design
• Lead-free finish compliant with RoHS directives

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

This component is officially marked as obsolete and discontinued by the manufacturer. Verify availability through authorized distributors or secondary markets. Confirm that the specific ordering suffix matches required packaging formats. Ensure compliance with end-use restrictions regarding life support systems.

Single Zener Diodes Selection Notes

Select this part only if legacy compatibility with the DO-35 form factor is mandatory. Evaluate surface mount equivalents like the MMSZ52xxB series for modern designs. Consider thermal derating requirements above 75°C ambient temperature during circuit planning.

Single Zener Diodes Part Context

The 1N5235B belongs to the 1N5221B through 1N5267B series of 500mW Zener diodes. This family offers a wide selection of voltages from 2.4V to 75V within the same hermetic glass package. The series is designed for applications requiring stable voltage references in harsh environments.

Single Zener Diodes Replacement Considerations

Diodes Incorporated recommends using the MMSZ52xxB series as direct replacements. These are surface mount equivalents available in SOD-123 packages. Verify pinout and thermal characteristics when transitioning from axial lead to surface mount technologies.
