1N5246BTR

Single Zener Diodes Overview

The Fairchild Semiconductor 1N5246BTR is a single Zener diode with a nominal voltage of 16 V and a maximum power dissipation of 500 mW. It features a ±5% tolerance and operates in the -65°C to +200°C range. The device utilizes a DO-35 axial through-hole package and exhibits a reverse leakage current of 100 nA at 10 V.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics
• Utilizes glass-sealed DO-35 axial package for robustness
• Supports high junction temperature operation up to 200°C

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the manufacturer designation, as the 1N5246B part number is widely produced by multiple semiconductor vendors including Rectron and Diodes Incorporated. Confirm that the specific B suffix indicates the required 5% tolerance level. Ensure the TR suffix aligns with the intended reel packaging format for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when a standard 16 V regulation point is required within a through-hole design. The 500 mW rating supports moderate current loads. Verify compatibility with the DO-35 footprint on the target PCB layout. Consider the 200°C thermal limit for high-temperature environments.

Single Zener Diodes Part Context

This component belongs to the standard 1N52xx series of 500 mW Zener diodes. These devices are commonly used for general-purpose voltage regulation. The 1N5246B variant specifically targets the 16 V market segment within the broader family of axial glass-passivated silicon junction diodes.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5246B parts. Verify pinout and package dimensions match the DO-35 specification. Check if alternative suppliers offer identical electrical parameters for direct substitution.
