1N4622 TR PBFREE

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4622 TR PBFREE is a silicon Zener diode designed for low leakage, low current, and low noise applications. It operates within the 1N4614 series range of 1.8V to 6.2V with a 5% tolerance. Key electrical parameters include a nominal Zener voltage (Vz) of 3.9V at a test current (Izt) of 250µA, a maximum Zener impedance (Zzt) of 5.0Ω, and a maximum reverse current (Ir) of 2.0µA at Vr=2.0V. The device dissipates 250mW, supports junction temperatures from -65°C to +200°C, and features a maximum forward voltage of 1.0V at 200mA.

Single Zener Diodes Feature Summary

• Engineered for low leakage and low noise performance suitable for sensitive circuits
• Provides stable voltage regulation with 5% tolerance across the operating temperature range
• Utilizes a DO-35 axial through-hole package for standard mounting configurations

Single Zener Diodes Applications

• Low noise voltage reference circuits
• Precision voltage regulation in low current environments
• Signal conditioning requiring minimal leakage current

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'TR PBFREE' corresponds to the tape-and-reel packaging format and lead-free plating requirements. Confirm that the manufacturer's datasheet for the 1N4614-4627 series remains the authoritative source for electrical limits and mechanical dimensions before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 3.9V Zener voltage is required with strict low-noise and low-leakage constraints. Ensure the application current does not exceed the 250mW power dissipation limit. Verify that the DO-35 package size fits the board layout and that the 5% voltage tolerance meets the circuit design margins.

Single Zener Diodes Part Context

This part belongs to the Central Semiconductor 1N4614 series of silicon Zener diodes, covering voltages from 1.8V to 6.2V. These devices are specifically characterized for low noise density, typically 1.0 µV/Hz at 250µA for this voltage range. The series is intended for applications where standard Zener noise levels would interfere with signal integrity.

Single Zener Diodes Replacement Considerations

Consult the manufacturer's datasheet for parameter-equivalent alternatives within the same series or other manufacturers' low-noise Zener diodes. Verify that any substitute matches the 3.9V nominal voltage, 250mW power rating, and DO-35 package outline.
