1N5085

Single Zener Diodes Overview

The 1N5085 is a fused-in-glass, metallurgically banded 3-watt Zener diode manufactured by New Jersey Semiconductor. It provides voltage regulation with a nominal Zener voltage of 50V and a tolerance of 5%. The device features a Case A axial package configuration. Key electrical characteristics include a continuous current rating defined by the power dissipation limit and a surge power capability that exceeds conventional 1-watt types by ten times. The component operates within a temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Fused-in-glass construction for enhanced reliability
• Metallurgically banded junction structure
• High surge current handling capacity relative to standard 1-watt types

Single Zener Diodes Applications

• Voltage regulation in high-power circuits
• Surge protection applications requiring robust transient handling
• Industrial equipment power supplies

Single Zener Diodes Procurement Notes

Verify the manufacturer designation carefully, as the 1N5085 part number is primarily associated with New Jersey Semiconductor rather than Microchip Technology. Confirm the specific datasheet version and physical dimensions (Case A) match your design requirements. Ensure the 3W power rating and 50V Zener voltage align with your circuit specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when a 3-watt power dissipation rating is required for voltage regulation tasks. The 50V nominal voltage with 5% tolerance suits applications needing precise reference levels. Consider the axial leaded package for through-hole mounting. Evaluate the thermal management needs given the 175°C maximum junction temperature capability and the fused-glass construction benefits.

Single Zener Diodes Part Context

This component belongs to the family of 3-watt power Zener diodes, specifically covering the 1N5063 through 1N5117 series. These devices are characterized by their fused-in-glass technology and metallurgical banding, offering superior performance compared to lower-power equivalents. The series provides a wide range of voltage options from 6.8V to 400V.

Single Zener Diodes Replacement Considerations

Cross-reference with other 3W Zener diodes in the 1N50xx series if voltage ratings differ. Verify pinout compatibility for axial packages. Check if alternative manufacturers offer equivalent fused-glass constructions with matching surge ratings.
