1N5253B-TR

Single Zener Diodes Overview

The Vishay 1N5253B-TR is a silicon planar power Zener diode with a nominal voltage of 25 V and a maximum power dissipation of 500 mW. It features a standard tolerance of ±5% and operates within a junction temperature range of -65 °C to +175 °C. The device utilizes the DO-35 (DO-204AH) axial through-hole package, weighs approximately 125 mg, and has a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Silicon planar construction for reliable voltage regulation
• Standardized ±5% Zener voltage tolerance
• High thermal stability across extended temperature ranges

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'B' suffix to confirm the required ±5% tolerance specification. Ensure the procurement documentation explicitly references the DO-35 (DO-204AH) glass encapsulation type. Confirm compliance with RoHS3 standards and material categorization requirements as defined in the official Vishay datasheet before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a 25 V reference point is required with moderate precision. The DO-35 package supports high peak soldering temperatures up to 260 °C. Consider the specific test current of 5 mA and dynamic resistance of 35 Ohms for circuit impedance matching. Verify that the ambient operating conditions remain within the specified thermal equilibrium limits.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.4 V to 75 V. The 'B' suffix indicates the standard tolerance grade, while other suffixes like 'C' denote tighter tolerances. These components are widely used in general-purpose electronic designs requiring stable DC voltage levels.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 25 V, 500 mW Zener diodes in the DO-35 package. Verify that substitute parts match the 35 Ohm dynamic resistance and 1.1 V forward voltage specifications to ensure circuit compatibility.
