1N4711 TR PBFREE

Overview

The Central Semiconductor Corp 1N4711 TR PBFREE is a silicon Zener diode designed for low-level voltage regulation applications. It operates within the 1N4678 through 1N4717 series, featuring a nominal Zener voltage of 27V with a 5% tolerance range spanning from 25.65V to 28.35V at a test current of 50μA. The device supports a maximum power dissipation of 500mW and maintains an operating junction temperature range of -65°C to +200°C. Packaged in the DO-35 axial leaded format, it exhibits a maximum reverse leakage current of 0.01μA at its rated voltage.

Feature Summary

• Engineered for extremely low operating currents and minimal leakage characteristics suitable for sensitive circuits
• Provides stable voltage regulation across a wide thermal operating range up to 200°C
• Utilizes a metallurgically bonded glass surface mount construction for durability

Applications

• Low-level voltage reference circuits
• Precision voltage regulation in low-power systems
• Protection against overvoltage transients in signal lines

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 RoHS3 compliance status directly with the supplier documentation before finalizing procurement orders.

Selection Notes

Select this component when circuit design requires a 27V Zener reference with tight tolerance and ultra-low leakage. The 50μA test current specification makes it distinct from standard high-current Zener diodes. Consider the DO-35 package constraints regarding board space and thermal management capabilities during the layout phase.
