1N4703 TR PBFREE

Overview

The Central Semiconductor Corp 1N4703 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 16 V with a 5% tolerance, tested at 50 μA. The device dissipates up to 500 mW and operates within a junction temperature range of -65°C to +200°C. Packaged in the DO-35 axial leaded case, it offers a maximum reverse leakage current of 0.05 μA and a maximum regulator current of 15.4 mA.

Feature Summary

Designed for applications requiring extremely low operating current (50μA) and low leakage.
Features a 5% voltage tolerance for precise regulation.
Capable of handling high junction temperatures 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. Ensure the package type matches the required DO-35 form factor for your assembly process. Confirm RoHS status through official datasheets or certificates before finalizing procurement specifications.

Selection Notes

Select this component when circuit design demands minimal quiescent current consumption alongside stable voltage regulation. The 500mW power rating supports moderate load requirements. Verify that the 16V nominal breakdown voltage aligns with the target protection or reference threshold.

Part Context

This part belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes. The series covers a voltage range from 1.8V to 43V, all sharing the same 500mW power dissipation capability and DO-35 mechanical outline. The 1N4703 specifically targets the 16V segment of this lineup.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4703 equivalents in DO-35 packages. Ensure replacement parts maintain the 500mW power rating and 5% tolerance to guarantee functional compatibility in existing designs.
