1N5232B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5232B/TR is a 0.5-watt glass axial-lead Zener diode in the DO-35 package, featuring a nominal Zener voltage of 6.0 volts at a test current of 20 mA. It offers a standard 5% tolerance (indicated by the 'B' suffix) and includes a tape-and-reel option ('TR'). The device operates within a temperature range of -65°C to +175°C, with a maximum reverse current of 7.0 µA at 4.8 volts and a Zener impedance of 5.0 ohms at 0.25 mA.

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
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation circuits requiring 6.0V reference
• Protection against overvoltage transients
• Clamping applications in electronic systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes required for your application. The 'B' suffix denotes a 5% voltage tolerance, while 'TR' indicates tape-and-reel packaging. Confirm RoHS compliance status if environmental regulations apply, as this is indicated by an 'e3' suffix in the series. Ensure the manufacturer source matches Microsemi/Microchip specifications for JEDEC registration and screening levels.

Single Zener Diodes Selection Notes

Select this component when a precise 6.0V Zener voltage with 5% tolerance is needed in a low-power 0.5W axial-lead form factor. Consider the DO-35 package constraints and thermal derating requirements for power dissipation. Evaluate the need for tighter tolerances or military screening if the standard B suffix does not meet circuit precision or reliability standards.

Single Zener Diodes Part Context

This part belongs to the popular 1N5221 through 1N5281B series of 0.5-watt Zener Voltage Regulators manufactured by Microsemi's Scottsdale Division. The series provides a wide selection of voltages from 2.4 to 200 volts in standard 5% or 10% tolerances. These devices are JEDEC registered and available in hermetically sealed glass DO-35 packages.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as MLL5232B in the DO-213AA MELF style package. Other voltage variants in the same series may serve as functional substitutes if voltage levels differ. Verify that any replacement maintains the required power dissipation and package compatibility.
