1N4730A BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N4730A BK TIN/LEAD is a silicon Zener diode with a nominal voltage of 3.9V and a maximum power dissipation of 1.0W at 50°C ambient temperature. It features a DO-41 glass case, operates within a junction temperature range of -65 to +200 °C, and has a test current of 64mA. The device exhibits a maximum Zener impedance of 9.0Ω, a reverse leakage current of 50µA at 1V, and a temperature coefficient ranging from -0.07% to -0.02% per degree Celsius.

Feature Summary

Provides reliable voltage regulation in industrial, commercial, entertainment, and computer applications
Features hermetically sealed glass compression bonded construction for corrosion resistance
Offers solderable terminals compliant with MIL-STD-202 method 208

Applications

Industrial circuit stabilization
Commercial voltage regulation
Entertainment system protection
Computer application clipping circuits

Procurement Notes

Verify the specific ordering suffix 'BK TIN/LEAD' to confirm the tin/lead plating option requested. Confirm availability status as this component may be subject to End of Life notices or discontinuation by the manufacturer. Ensure compatibility with existing leaded soldering processes if transitioning from lead-free alternatives.

Selection Notes

Select this component when a 3.9V Zener reference is required in a through-hole DO-41 package. Consider the negative temperature coefficient for low-voltage operation. Verify that the 1.0W power rating meets the thermal requirements of the target application environment.

Part Context

This part belongs to the 1N4728A through 1N4764A series of 1-watt silicon Zener diodes manufactured by Central Semiconductor Corp. The series provides a wide selection of voltages from 3.3V to 100V with standard 5% tolerance. These devices are designed for general-purpose voltage regulation tasks.
