1N4372A/TR

Single Zener Diodes Overview

The 1N4372A/TR is a single silicon Zener diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-204AH (DO-35) axial package. It features a nominal Zener voltage of 3 V with a tolerance of ±5% and a maximum impedance of 29 Ohms. The device supports a forward current of 200 mA at a forward voltage of 1.1 V and exhibits a reverse leakage current of 30 µA at 1 V. Operating within a temperature range of -65°C to 175°C, it is supplied in tape and reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via unidirectional Zener breakdown characteristics
• Constructed with silicon junction technology for reliable performance
• Capable of operation across extended industrial temperature ranges

Single Zener Diodes Applications

• Voltage reference circuits requiring precise low-voltage regulation
• Protection against overvoltage transients in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix /TR corresponds to the tape and reel packaging format required for automated assembly processes. Confirm compliance status and environmental certifications directly with the manufacturer documentation, as regulatory attributes may vary between production runs or regional manufacturing sites.

Single Zener Diodes Selection Notes

Select this component when a fixed 3 V reference point is necessary within a through-hole design constraint. Ensure the circuit can accommodate the specified 29 Ohm impedance and 30 µA leakage current. Verify that the thermal management strategy supports the 175°C maximum junction temperature rating during continuous operation.

Single Zener Diodes Part Context

This part belongs to the standard 1N437x series of Zener diodes produced by Microchip Technology. It shares electrical specifications with other variants in the family but differs in packaging configuration. The /TR suffix specifically denotes the bulk reel supply method, distinguishing it from loose bulk or individual tube distributions.

Single Zener Diodes Replacement Considerations

JAN1N4372A-1 offers equivalent electrical parameters in a through-hole DO-35 package, though it lacks the tape and reel packaging format.
