1N4617 TR PBFREE

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4617 TR PBFREE is a silicon Zener diode designed for low leakage, low current, and low noise applications. It operates within the 1.8V to 6.2V range with a nominal Zener voltage of 2.4V at a test current of 250µA. The device features a maximum power dissipation of 250mW and a tight tolerance of ±5%. It utilizes a DO-35 axial leaded package and supports an operating junction temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Engineered specifically for low noise environments with a noise density of 1.0 µV/Hz at 250µA.
• Optimized for low leakage and low current operation suitable for sensitive circuits.
• Provides precise voltage regulation with a standard 5% tolerance band.

Single Zener Diodes Applications

• Low noise reference voltage generation
• Precision voltage clamping in signal paths
• Over-voltage protection for sensitive low-current components

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'PBFREE' corresponds to lead-free plating as defined by manufacturer standards. Confirm the 'TR' designation indicates tape and reel packaging if automated assembly is required. Ensure the specific lot markings align with the C4617 code specified in the datasheet electrical characteristics table.

Single Zener Diodes Selection Notes

Select this component when circuit requirements demand minimal noise contribution alongside stable voltage regulation. The 250mW power rating limits suitability to low-current scenarios. Verify that the DO-35 through-hole package fits the mechanical constraints of the target PCB layout compared to surface mount alternatives.

Single Zener Diodes Part Context

This part belongs to the 1N4614 through 1N4627 series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers voltages from 1.8V to 6.2V and is characterized by its low noise profile. These devices are distinct from higher voltage options like the 1N4099 series and are housed in the standard DO-35 case outline.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent replacements include other manufacturers' 1N4617 variants. Ensure substitute parts maintain the 250mW power dissipation limit and DO-35 package dimensions. Verify that replacement noise density and impedance specifications meet the original design's low-noise requirements.
