1N5252BRL

Single Zener Diodes Overview

The Motorola 1N5252BRL is a silicon unidirectional voltage regulator diode designed for general-purpose applications. It operates within the DO-35 (DO-204AH) glass axial-lead package, featuring two terminals and an isolated case connection. The device provides a nominal Zener voltage of 5.1V with a maximum power dissipation of 500mW. It maintains a tolerance of ±5% and exhibits a knee impedance of 50 Ohms. The component supports a wide operating temperature range from -65°C to +200°C junction temperature.

Single Zener Diodes Feature Summary

• Hermetically sealed double slug type construction utilizing metallurgically bonded glass materials
• Corrosion-resistant external surfaces with readily solderable leads for reliable assembly
• Compact DO-204AH package design offering reduced physical footprint compared to conventional DO-204AA configurations

Single Zener Diodes Applications

• Voltage regulation in low-power electronic circuits
• Reference voltage generation for analog signal processing
• Overvoltage protection in sensitive semiconductor interfaces

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N5252BRL designation appears across multiple vendors including Motorola/NXP and Microsemi/ON Semiconductor. Confirm that the DO-35 package and 5.1V specification align with your schematic requirements. Ensure compliance with any applicable environmental regulations or military screening levels if required by your system specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a standard 5.1V reference is needed in a compact axial-lead form factor. The 500mW power rating suits low-current applications where thermal management is limited. Consider the ±5% tolerance for general regulation tasks. Verify lead soldering temperature limits of 230°C at 1/16 inch from the case for ten seconds during assembly processes to prevent package damage.

Single Zener Diodes Part Context

This part belongs to the widely utilized 1N52xx series of 500mW Zener diodes. Originally introduced by Motorola and now produced by various manufacturers like ON Semiconductor and Microsemi, these components serve as industry-standard voltage references. The BRL suffix typically indicates a reel packaging format, distinguishing it from bulk or tape-and-reel variations found in other supply chains.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5252B and 1N5252A variants, which share identical electrical characteristics but may differ in tolerance or packaging. Cross-reference with ON Semiconductor's 1N5252BRLG for RoHS-compliant versions. Ensure replacement parts maintain the DO-35 package dimensions and hermetic sealing properties.
