1N4735A BK PBFREE

Overview

The Central Semiconductor Corp 1N4735A BK PBFREE is a silicon Zener diode designed for voltage regulation. It features a nominal Zener voltage of 6.2 V with a ±5% tolerance, operating within a range of 5.890 V to 6.510 V at a test current of 41 mA. The device dissipates up to 1.0 W at 50°C and maintains an operating temperature range from -65°C to +200°C. Electrical characteristics include a maximum reverse current of 10 μA at 3.0 V and a DC current rating of 700 mA. It utilizes the DO-41 axial through-hole package.

Feature Summary

• Provides stable voltage regulation using silicon junction technology
• Features a hermetically sealed glass body in a standard DO-41 axial leaded package
• Designed for industrial, commercial, entertainment, and computer applications

Applications

• Low voltage stabilizers
• Voltage reference circuits
• Industrial control systems

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation before procurement. Confirm that the 'BK' designation corresponds to bulk packaging requirements and that the 'PBFREE' suffix aligns with RoHS compliance standards. Ensure the component matches the exact electrical parameters required for the target circuit design.

Selection Notes

Select this component when a precise 6.2 V reference is needed with high power dissipation capabilities. The wide operating temperature range supports demanding environments. Verify that the DO-41 package dimensions fit the available board space and that the thermal management strategy accommodates the 1.0 W power rating under expected load conditions.
