1N5232A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5232A/TR is a Zener diode with a nominal voltage of 5.6 V and a tolerance of ±10%. It operates in the DO-35 (DO-204AH) glass axial-lead package, dissipating up to 0.5 W at 25°C. The device features a maximum reverse current of 1600 μA at 4.7 V and a dynamic impedance of 11 Ω at 20 mA. It supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Hermetically sealed glass DO-35 package for reliable performance
• Inherently radiation hard per MicroNote 050
• Minimal capacitance characteristics

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the part number includes the TR suffix to confirm tape and reel packaging compliance with EIA-296 standards. Ensure the A suffix is present to match the required ±10% voltage tolerance specification. Confirm RoHS compliance status if environmental restrictions apply to your assembly process.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V reference with ±10% tolerance is required in a through-hole axial configuration. Consider the 0.5 W power dissipation limit and derating curves for thermal management. Verify that the DO-35 package dimensions fit the PCB layout constraints.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 to 200 volts. The 1N5232A variant specifically targets applications requiring a 5.6 V breakdown voltage with standard commercial tolerances.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5232B for tighter ±5% tolerance or 1N5232C/D for ±2%/±1% tolerance. Surface mount equivalents are available as MLL5232 in the DO-213AA MELF style package.
