1N4714 TR PBFREE

Overview

The Central Semiconductor Corp 1N4714 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 33 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. It utilizes a DO-35 axial through-hole 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 handling high thermal stress with an extended operating junction temperature range.

Applications

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

Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape-and-reel packaging and 'PBFREE' confirms lead-free plating as per manufacturer standards. Confirm the specific reel quantity requirements with the distributor or manufacturer prior to purchase, as standard packaging quantities may vary by production batch.

Selection Notes

Select this component when circuit design demands minimal quiescent current draw alongside precise voltage clamping. The DO-35 package is suitable for through-hole mounting. Ensure the maximum regulator current of 7.2 mA aligns with the available series resistance in the target application to prevent exceeding power dissipation limits.
