1N4737A TR PBFREE

Overview

The Central Semiconductor Corp 1N4737A TR PBFREE is a silicon Zener diode in the DO-41 axial leaded package. It provides a nominal voltage of 7.5 V with a 5% tolerance range (7.125 V to 7.875 V). The device dissipates up to 1.0 W at 50°C and operates within a temperature range of -65°C to +200°C. Key electrical parameters include a maximum reverse current of 10 μA, a maximum DC current of 5.0 mA, and a temperature coefficient between +0.02% and +0.065% per °C.

Feature Summary

Provides stable voltage regulation for industrial and commercial circuits
Features high reliability and robust thermal performance
Utilizes a standard DO-41 glass body package

Applications

Industrial equipment power supplies
Commercial electronic systems
Computer applications requiring voltage reference

Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape-and-reel packaging as specified by the manufacturer. Confirm the 'PBFREE' designation aligns with RoHS compliance requirements for your assembly process. Ensure the component matches the specific DO-41 mechanical outline and electrical characteristics detailed in the official datasheet before finalizing procurement.

Selection Notes

Select this component when a 7.5 V Zener reference is required in an axial leaded format. Consider the 1.0 W power dissipation limit and the -65°C to +200°C operating range for environmental suitability. Verify that the 5% voltage tolerance meets the precision requirements of the target circuit design.

Part Context

This part belongs to the 1N4728A through 1N4764A series of 1-watt silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 3.3 V to 100 V with consistent 5% tolerance across all variants.
