1N4683 TR PBFREE

Overview

The Central Semiconductor Corp 1N4683 TR PBFREE is a silicon Zener diode designed for low-level applications requiring extremely low operating current and leakage. It features a nominal Zener voltage of 3.0 V with a 5% tolerance, tested at a current of 50 μA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +200°C. It utilizes the DO-35 axial leaded package.

Feature Summary

• Designed for applications requiring extremely low operating current (50μA) and low leakage.
• Provides stable voltage regulation with a tight 5% tolerance on the nominal Zener voltage.
• Capable of operation across an extended temperature range from -65°C to +200°C.

Applications

• Low-level voltage reference circuits
• Precision voltage regulation in sensitive electronics
• Protection against overvoltage in low-power systems

Procurement Notes

Verify that the ordering suffix 'PBFREE' corresponds to lead-free plating as defined by the manufacturer's standard terms. Confirm the package type matches the required DO-35 axial leaded form factor. Ensure the component meets RoHS compliance requirements for your specific manufacturing process.

Selection Notes

Select this component when circuit design demands minimal quiescent current draw alongside precise voltage clamping. The 500mW rating suits moderate power dissipation needs. Verify that the 3.0V nominal voltage aligns with the target regulation point and that the DO-35 package fits the board layout constraints.

Part Context

This part belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 1.8V to 43V, all sharing similar electrical characteristics regarding test currents and leakage specifications while differing primarily in their nominal breakdown voltages.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4683 variants or equivalent Zener diodes with matching 3.0V nominal voltage, 500mW power rating, and DO-35 package dimensions. Cross-reference datasheets to ensure identical leakage and tolerance specifications are met.
