1N4619 TR PBFREE

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4619 TR PBFREE is a silicon Zener diode designed for low leakage, low current, and low noise applications. It operates within the 1N4614 series range, featuring a nominal Zener voltage of 3.0 V with a 5% tolerance. The device dissipates up to 250 mW at 25°C and maintains a junction temperature range from -65°C to +200°C. Electrical characteristics include a maximum reverse current of 0.8 µA at 1.0 V and a maximum Zener impedance of 1600 Ω at a test current of 250 µA. Noise density is specified at 1.0 µV/Hz at 250 µA.

Single Zener Diodes Feature Summary

Single Zener Diodes Applications

• Low noise signal conditioning
• Precision voltage reference circuits
• Low current regulation tasks

Single Zener Diodes Procurement Notes

Verify that the ordering suffix PBFREE corresponds to lead-free plating as defined by the manufacturer's standard terms. Confirm the specific reel quantity requirements for automated assembly processes. Ensure the DO-35 package dimensions align with the target PCB footprint. Cross-reference the C4619 marking code against incoming inspection standards to validate authenticity and traceability.

Single Zener Diodes Selection Notes

Select this component when circuit design requires a stable 3.0 V reference with minimal noise interference. The 250 mW power rating supports moderate current levels without excessive thermal management. Consider the 1600 Ω impedance value for high-impedance source applications. The wide temperature range ensures reliability across diverse environmental conditions.

Single Zener Diodes Part Context

This part belongs to the Central Semiconductor 1N4614 through 1N4627 series of silicon Zener diodes. The series covers voltages from 1.8 V to 6.2 V, all sharing identical mechanical outlines and general electrical profiles. Higher voltage options are available in the separate 1N4099 series. The 1N4619 specifically targets the 3.0 V segment of this low-noise lineup.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4619 variants such as those from Microchip Technology or Nexperia. Verify that replacement parts maintain the same 250 mW dissipation, DO-35 package, and 5% tolerance specifications.
