1N5246

Single Zener Diodes Overview

The SMC Diode Solutions 1N5246 is a single silicon unidirectional voltage regulator diode designed for through-hole mounting in the DO-35 (DO-204AH) glass axial package. It provides a nominal Zener voltage of 16 V with a power dissipation rating of 500 mW. The device features a tight voltage tolerance of 5%, a maximum reverse leakage current of 100 nA, and a Zener impedance of 17 Ohms at a test current of 7.8 mA. It operates within a junction temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Utilizes a hermetically sealed glass axial construction for robust environmental protection
• Provides stable voltage regulation with a narrow 5% tolerance band
• Engineered for high thermal stability with an extended maximum operating temperature

Single Zener Diodes Applications

• Lithium battery-powered device circuits
• High-quality tube amplifier biasing networks
• General-purpose voltage reference applications

Single Zener Diodes Procurement Notes

Verify specific manufacturing lot dates and RoHS compliance status directly with the supplier or manufacturer before integration. Confirm that the DO-35 axial lead form factor matches the target PCB footprint requirements. Ensure the 500 mW power rating aligns with the expected thermal environment and derating curves for the final assembly.

Single Zener Diodes Selection Notes

Select this component when a standard 16 V regulation point is required in a through-hole design. The DO-35 package offers reliable performance for general electronics where surface mount space is not constrained. Consider the 17 Ohm impedance value for noise-sensitive linear applications requiring low dynamic resistance.

Single Zener Diodes Part Context

This part belongs to the widely recognized 1N52xx series of small-signal Zener diodes. Manufactured by SMC Diode Solutions, it serves as a direct functional equivalent to parts from other major semiconductor vendors such as onsemi and Microchip. The 1N5246 designation specifically identifies the 16 V variant within this standardized regulatory family.

Single Zener Diodes Replacement Considerations

Direct cross-references include the onsemi 1N5246B and the Microchip 1N5246BUR-1. These alternatives share identical electrical specifications but may differ in physical packaging, such as bulk versus reel formats, or mounting styles like surface mount variants.
