1N4619 BK TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4619 BK TIN/LEAD is a single silicon Zener diode housed in a DO-35 through-hole package. It features a nominal Zener voltage of 3.0 V with a 5% tolerance and a power dissipation rating of 250 mW. Key electrical parameters include a maximum reverse leakage current of 0.8 µA, a Zener impedance of 1600 Ohms, and a test current of 250 µA. The device operates within a temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a low 3.0 V reference level for precision circuits.
• Utilizes a rugged DO-35 axial leaded package designed for reliable through-hole mounting.
• Constructed from high-purity silicon to ensure consistent performance across wide thermal ranges.

Single Zener Diodes Applications

• Low-voltage reference sources in analog signal conditioning circuits
• Voltage clamping and protection stages in sensitive electronic inputs
• Biasing networks requiring precise low-level DC potential

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required termination finish, as tin/lead variants differ from lead-free options. Confirm that the DO-35 package dimensions align with your PCB footprint constraints. Ensure the 250 mW power rating suffices for your thermal environment, as derating may be necessary above 50°C. Cross-reference the manufacturer's datasheet for exact mechanical tolerances before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a low-cost, standard Zener voltage is required for non-critical regulation tasks. The 1N4619 offers a balance of availability and basic performance suitable for general-purpose electronics. Consider higher-power variants if the application demands greater thermal stability or lower impedance characteristics than those provided by the 250 mW rating.

Single Zener Diodes Part Context

This part belongs to the widely recognized 1N46xx series of low-power Zener diodes. These components are standardized for basic voltage regulation needs across various industries. The Central Semiconductor variant maintains compatibility with traditional through-hole assembly processes while offering specific material compositions for reliability.

Single Zener Diodes Replacement Considerations

Direct replacements include the Microchip Technology 1N4619-1, which shares similar electrical characteristics but offers a 500 mW power rating. Other generic equivalents within the 1N46xx series may be substituted if pinout and voltage specifications match exactly.
