1N4735A TR PBFREE

Overview

The Central Semiconductor Corp 1N4735A TR PBFREE is a silicon Zener diode designed for voltage regulation in industrial, commercial, entertainment, and computer applications. It features a nominal Zener voltage of 6.2 V with a 5% tolerance range from 5.890 V to 6.510 V. The device operates at a test current of 41 mA and dissipates up to 1.0 W at 50°C ambient temperature. It utilizes the DO-41 axial through-hole package and supports an operating and storage temperature range from -65°C to +200°C.

Feature Summary

• Highly reliable voltage regulation suitable for diverse electronic environments
• Robust thermal performance supporting extended operating temperatures up to 200°C
• Standardized axial leaded construction for straightforward circuit integration

Applications

• Industrial equipment power supplies
• Commercial electronics control circuits
• Entertainment system voltage references
• Computer peripheral protection

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating specifications. The PBFREE designation indicates lead-free compliance. Confirm that the TR suffix aligns with the required bulk packaging format for your assembly process. Ensure compatibility with standard axial mounting techniques before finalizing procurement orders.

Selection Notes

Select this component when a stable 6.2 V reference is required within a 5% tolerance band. The 1.0 W power rating allows for significant current handling in series configurations. Verify that the maximum reverse leakage current and impedance values meet the specific noise and stability requirements of the target application circuit design.
