1N5228A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5228A/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 package, featuring a nominal voltage of 3.9 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 flexible axial-lead mounting terminals for through-hole applications
• Offers minimal capacitance characteristics suitable for various circuit requirements

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin as datasheets may reference Microsemi or Microchip due to corporate acquisition history. Confirm that the TR suffix correctly denotes tape-and-reel packaging per EIA-296 standards before ordering. Ensure compatibility with RoHS compliance requirements if applicable to your assembly process.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V Zener voltage with ±10% tolerance is required. The DO-35 package suits standard through-hole layouts. Consider the power derating curve for thermal management above 50°C lead temperature. Verify impedance and leakage current specifications against circuit sensitivity requirements.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 W Zener diodes. The series provides a wide selection of voltages from 2.4 V to 200 V. Standard tolerances are available with B (±5%) or A (±10%) suffixes, while tighter tolerances use C or D suffixes.

Single Zener Diodes Replacement Considerations

Consult official cross-reference lists for equivalent parts. Generic replacements must match the 3.9 V nominal voltage, 500 mW power rating, and DO-35 package dimensions.
