1N4710 TR PBFREE

Overview

The Central Semiconductor Corp 1N4710 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 25 V with a 5% tolerance, tested at 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. Packaged in the DO-35 axial leaded format, it offers a maximum reverse leakage current of 0.01 μA and a maximum regulator current of 9.5 mA.

Feature Summary

• Designed for applications requiring extremely low operating current and low leakage
• Provides stable voltage regulation with tight 5% tolerance
• Capable of operation across an extended temperature range up to +200°C

Applications

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

Procurement Notes

Verify that the ordering suffix 'PBFREE' confirms lead-free plating compliance as specified by the manufacturer. Confirm the package type matches the required DO-35 form factor for your assembly process. Ensure the specific part number corresponds to the 25V nominal voltage variant within the 1N4678 through 1N4717 series.

Selection Notes

Select this component when circuit design demands minimal quiescent current consumption alongside precise voltage clamping. The 500 mW power rating allows for moderate current handling in compact axial packages. Consider the low leakage characteristics for high-impedance signal paths where standard Zener diodes might introduce unacceptable error currents.

Part Context

This device belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes from Central Semiconductor. The series covers a voltage range from 1.8 V to 43 V, all sharing common electrical characteristics such as 50 μA test current and 5% tolerance. These parts are standardized for general-purpose voltage regulation tasks in consumer and industrial electronics.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4710 equivalents in DO-35 packages. Verify that substitute parts maintain the 25 V nominal voltage, 500 mW power rating, and 5% tolerance specifications to ensure functional compatibility.
