1N5246B_S00Z

Single Zener Diodes Overview

The onsemi 1N5246B is a single-channel general-purpose Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 16 V with a tight tolerance of ±5%. The device supports a maximum power dissipation of 500 mW and operates within an extended temperature range from -65 °C to +200 °C. Packaged in the DO-35 (SOD-27) through-hole format, it exhibits a low reverse leakage current of 100 nA and a Zener impedance of 17 Ohms at a test current of 7.8 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal 16 V breakdown point.
• Engineered for high thermal stability across a wide operating temperature range.
• Utilizes planar die construction for reliable performance in through-hole assemblies.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in electronic systems.

Single Zener Diodes Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact packaging or marking variations. Ensure compatibility with existing board layouts regarding the DO-35 footprint dimensions. Cross-reference RoHS and REACH compliance status directly with the supplier's latest certification documents prior to procurement.

Single Zener Diodes Selection Notes

Select this component when a robust through-hole solution is required for 16 V regulation tasks. The 500 mW power rating suits moderate current applications without excessive heat sinking. Consider the ±5% tolerance for precision requirements and verify that the 17 Ohm impedance meets the dynamic load specifications of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the widely recognized 1N52xx series of silicon Zener diodes manufactured by onsemi. The series offers various voltage options within a standardized axial leaded package.
