1N5253B

Single Zener Diodes Overview

The SMC Diode Solutions 1N5253B is a unidirectional Zener diode housed in a DO-35 glass axial package. It features a nominal breakdown voltage of 26V with a tolerance of 5%. The device is rated for a maximum power dissipation of 0.5W and operates at a test current of 5mA. Designed for through-hole mounting, it provides reliable voltage regulation within its specified thermal limits.

Single Zener Diodes Feature Summary

• Unidirectional Zener configuration for precise voltage reference applications
• DO-35 glass axial encapsulation ensuring robust environmental stability
• Standardized 5% voltage tolerance for consistent circuit performance

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection systems
• General-purpose discrete semiconductor applications

Single Zener Diodes Procurement Notes

Verify the manufacturer designation carefully, as Sensitron is listed as the producer in available documentation while SMC Diode Solutions is requested. Confirm the DO-35 package type and 26V rating match specific design requirements before procurement to ensure compatibility with existing board layouts.

Single Zener Diodes Selection Notes

Select this component when a 26V unidirectional Zener reference is required in an axial glass package. Ensure the circuit can handle the 0.5W power dissipation limit and that the 5mA test current aligns with the intended operating conditions for accurate voltage clamping.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode category, widely used for basic voltage stabilization tasks. The DO-35 form factor is common in legacy and general-purpose electronics, offering a compact solution for low-power regulation needs compared to larger through-hole alternatives.

Single Zener Diodes Replacement Considerations

Substitutes must maintain the 26V nominal breakdown voltage, 5% tolerance, 0.5W power rating, and DO-35 axial glass package to ensure direct pinout and electrical compatibility without redesigning the host circuit.
