1N4618 TR PBFREE

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4618 TR PBFREE is a silicon Zener diode designed for low leakage, low current, and low noise applications. It features a nominal Zener voltage of 2.7 V with a 5% tolerance range from 2.565 V to 2.835 V at a test current of 250 µA. The device operates within a power dissipation limit of 250 mW and supports junction temperatures from -65°C to +200°C. Key electrical specifications include a maximum Zener impedance of 1500 Ω, a maximum reverse current of 1.0 µA, and a maximum noise density of 1.0 µV/√Hz at 250 µA.

Single Zener Diodes Feature Summary

• Engineered for low leakage and low noise performance suitable for sensitive signal conditioning
• Provides stable voltage regulation within a tight 5% tolerance band
• Capable of operation across an extended temperature range up to 200°C

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix required for your assembly process. Use 'PBFREE' for lead-free compliant devices or 'TIN/LEAD' for tin-lead plated variants as specified in the manufacturer's ordering guidelines. Confirm that the reel packaging matches your automated placement equipment requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when circuit design demands low noise characteristics alongside precise voltage clamping. The 2.7 V nominal rating fits specific low-voltage regulation needs. Ensure the 250 mW power dissipation capability aligns with thermal management constraints in the target application environment.

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 1.8 V to 6.2 V, all sharing similar low-noise and low-leakage design parameters. These devices are housed in the DO-35 axial leaded package, providing a standard form factor for through-hole mounting.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged Zener diodes with equivalent 2.7 V ratings. Verify that substitute components meet the same 1500 Ω impedance and 1.0 µA reverse current limits to maintain circuit performance integrity.
