1N4680 BK PBFREE

Overview

The Central Semiconductor Corp 1N4680 BK PBFREE is a low-level silicon Zener diode housed in a DO-35 case. It provides a nominal Zener voltage of 2.2 V with a tolerance range of 2.090 V to 2.310 V at a test 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. Key electrical characteristics include a maximum reverse leakage current of 4.0 μA, a maximum regulator current of 100.0 mA, and a maximum voltage change of 0.75 V.

Feature Summary

• Designed for applications requiring extremely low operating currents and minimal leakage.
• Features a standard DO-35 axial leaded package suitable for through-hole mounting.
• Provides stable voltage regulation across a wide operating and storage temperature range.

Applications

• Low-level voltage reference circuits
• Precision voltage regulation
• Protection against overvoltage conditions

Procurement Notes

Verify the specific ordering suffix requirements when placing orders. The 'PBFREE' designation indicates lead-free plating compliance. Confirm that the requested quantity aligns with manufacturer packaging standards. Ensure compatibility with RoHS directives if required by your project specifications. Contact the manufacturer or authorized distributors directly for availability and technical support inquiries.

Selection Notes

Select this component when a precise 2.2 V reference is needed with minimal quiescent current consumption. The DO-35 package offers a compact form factor for general-purpose electronics. Consider the 5% voltage tolerance and the 50 μA test current requirement during circuit design. Ensure the thermal environment remains within the specified -65°C to +200°C junction temperature limits for reliable operation.

Part Context

This part belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes manufactured by Central Semiconductor. The series covers a voltage range from 1.8 V to 43 V, all sharing similar low-current operational characteristics and DO-35 packaging. These devices are engineered specifically for precision applications where low power consumption and tight voltage stability are critical design parameters.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4680 equivalents in DO-35 packages. Verify that substitute parts meet the 2.2 V nominal voltage, 500 mW power rating, and 5% tolerance specifications. Ensure the replacement device maintains comparable leakage current and temperature coefficient characteristics for direct interchangeability.
