1N4717 TR PBFREE

Overview

The Central Semiconductor Corp 1N4717 TR PBFREE is a silicon Zener diode designed for low-level voltage regulation applications. It operates within the 1N4678 through 1N4717 series, featuring a nominal Zener voltage of 43 V with a tolerance of ±5%. The device dissipates up to 500 mW and maintains operation across a junction temperature range of -65°C to +200°C. Electrical characteristics include a maximum reverse leakage current of 0.01 μA at 45.15 V and a test current of 50 μA. The component utilizes a DO-35 axial leaded package.

Feature Summary

• Designed for extremely low operating current requirements
• Features low leakage current specifications
• Provides stable voltage regulation within tight tolerance limits

Applications

• Low power voltage reference circuits
• Precision voltage regulation in sensitive electronics
• Overvoltage protection for low-current signals

Procurement Notes

Verify that the ordering suffix matches the required plating configuration. The PBFREE designation indicates lead-free plating compliance. Confirm the specific tape and reel packaging quantity aligns with production needs. Ensure the manufacturer part number corresponds exactly to the 1N4717 specification before procurement.

Selection Notes

Select this component when a precise 43 V reference is required with minimal quiescent current draw. The low leakage characteristic makes it suitable for high-impedance circuits. Consider the DO-35 package constraints for board layout. Evaluate thermal dissipation capabilities relative to ambient operating conditions.

Part Context

This device belongs to the 1N4678 through 1N4717 series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 1.8 V to 43 V. All devices in this family share similar electrical profiles, including 500 mW power dissipation and 5% tolerance, differing primarily in their specific Zener voltage ratings.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4717 equivalents in DO-35 packages. Verify that substitute components meet the same 500 mW power rating and 43 V nominal voltage specifications. Ensure compatibility with the low leakage current requirements of the original design.
