1N5985/TR

Single Zener Diodes Overview

The Microchip Technology 1N5985/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 2.4 V with a tight tolerance of 2%. The component is rated for a maximum power dissipation of 0.48 W and operates within an extended temperature range from -65°C to +175°C. Packaged in the DO-35 axial leaded format, it exhibits a maximum reverse leakage current of 15 µA at 1 V and a Zener impedance of 90 Ohms at a test current of 5 mA. The forward voltage drop is specified as 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 2% tolerance on the 2.4 V Zener voltage.
• Supports high-temperature operation up to 175°C for demanding environments.
• Utilizes a glass axial-leaded DO-35 package for through-hole mounting.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with design requirements. Confirm RoHS compliance status and manufacturing origin details prior to procurement. Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability. Ensure storage conditions meet moisture sensitivity level specifications upon receipt.

Single Zener Diodes Selection Notes

Select this component when a stable 2.4 V reference is required with tight tolerance constraints. Consider the DO-35 package dimensions for PCB layout clearance. Evaluate the thermal management capabilities given the 0.48 W power rating and operating temperature range. Compare leakage current specifications against circuit sensitivity requirements.

Single Zener Diodes Part Context

This device belongs to the 1N5985 series of 0.5 watt Zener Voltage Regulators manufactured by Microchip Technology. The series offers a wide selection of voltages ranging from 2.4 to 200 volts in standard tolerances. These components are widely used in industrial and commercial electronics requiring reliable voltage clamping or referencing.

Single Zener Diodes Replacement Considerations

Consult official substitution lists for parameter-equivalent alternatives. Verify that any substitute matches the 2.4 V Zener voltage, 2% tolerance, and DO-35 package form factor. Ensure thermal and electrical characteristics align with original design specifications.
