1N4716 TR PBFREE

Overview

The Central Semiconductor Corp 1N4716 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 39 V with a tolerance range of 37.05 V to 40.95 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. It utilizes the DO-35 axial leaded package and is supplied in reel packaging.

Feature Summary

• Designed for applications requiring extremely low operating current and low leakage characteristics
• Provides stable voltage regulation with a tight 5% tolerance band
• Capable of handling high thermal stress with an extended junction temperature range

Applications

• Low-level voltage reference circuits
• Precision voltage regulation requiring minimal bias current
• Protection against overvoltage transients in sensitive electronics

Procurement Notes

Verify that the ordering suffix PBFREE corresponds to lead-free plating as defined by manufacturer standards. Confirm the reel packaging configuration matches automated assembly requirements. Ensure the specific part number aligns with the DO-35 mechanical outline and electrical specifications provided in the official datasheet before finalizing procurement.

Selection Notes

Select this component when circuit design demands a 39 V Zener reference with minimal quiescent current draw. The 50 μA test current specification makes it suitable for battery-powered or energy-efficient systems. Verify that the 500 mW power rating accommodates the expected load conditions and ambient thermal environment without exceeding the maximum junction temperature limits.

Part Context

This component 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 1.8 V to 43 V, all sharing similar low-current operational characteristics and the DO-35 axial leaded package format for through-hole mounting applications.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4716 equivalents in the DO-35 package. Ensure substitute parts meet the 39 V nominal voltage, 500 mW power dissipation, and 50 μA test current specifications to maintain circuit performance integrity.
