1N5246A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5246A/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 package, featuring a nominal voltage of 16 V with ±10% tolerance (suffix A). It operates within a temperature range of -65°C to +175°C and includes a tape-and-reel option indicated by the TR suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features minimal capacitance for high-frequency applications
• Inherently radiation hard per MicroNote 050

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the datasheet to ensure correct tolerance and packaging options. Confirm that the TR suffix aligns with automated assembly needs. Cross-reference the manufacturer's latest documentation for any updates on screening levels or material compliance before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a standard 16 V Zener voltage with 10% tolerance is required in an axial-lead package. Consider the power derating curve if ambient temperatures exceed 25°C. Ensure the application does not require tighter tolerances than the 'A' suffix provides.

Single Zener Diodes Part Context

This device belongs to the popular 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection from 2.4 to 200 volts in standard 5% or 10% tolerances. These glass axial-leaded DO-35 Zeners are JEDEC registered and widely used in general electronic applications.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as MLL5246A in the DO-213AA MELF style package. Other variants within the 1N5221-1N5281B series may be considered if different voltage ratings are needed.
