1N4702 TR PBFREE

Overview

The Central Semiconductor Corp 1N4702 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 15 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. It utilizes the DO-35 axial leaded package.

Feature Summary

• Designed for applications requiring extremely low operating current (50μA) and low leakage.
• Provides stable voltage regulation with a tight 5% tolerance on the nominal Zener voltage.
• Capable of high-temperature operation up to +200°C junction temperature.

Applications

• Low-level voltage reference circuits
• Precision voltage regulation in sensitive electronics
• Protection against overvoltage in low-current systems

Procurement Notes

Verify that the ordering suffix 'TR PBFREE' corresponds to the specific tape-and-reel packaging and lead-free plating requirements. Confirm the manufacturer's part number matches the datasheet exactly. Ensure the component meets RoHS compliance standards if required by your assembly process. Cross-reference the marking code C4702 for physical identification upon receipt.

Selection Notes

Select this component when circuit design demands minimal quiescent current draw alongside precise voltage clamping. The 500mW rating suits moderate power dissipation needs. Verify that the 15V nominal voltage aligns with system requirements. Consider the DO-35 package constraints for PCB layout and thermal management during selection.
