1N4738A TR PBFREE

Overview

The Central Semiconductor Corp 1N4738A TR PBFREE is a silicon Zener diode in the DO-41 axial leaded package. It provides an 8.2 V nominal Zener voltage with a ±5% tolerance, tested at 31 mA. The device dissipates up to 1.0 W at 50°C and operates from -65°C to +200°C. Electrical characteristics include a maximum Zener impedance of 4.5 Ω at test current and 700 Ω at knee current, alongside a maximum reverse leakage current of 10 μA at 7.6 V.

Feature Summary

Highly reliable voltage regulation for industrial and commercial applications
Glass passivated junction ensuring high temperature soldering capability
Low Zener impedance for stable performance

Applications

Industrial equipment voltage regulation
Commercial power supply circuits
Entertainment system protection
Computer application voltage references

Procurement Notes

Verify the exact ordering suffix against official documentation before procurement. Confirm that the 'TR' designation aligns with required tape-and-reel packaging specifications. Ensure the 'PBFREE' suffix matches environmental compliance requirements. Cross-reference the manufacturer part number directly with the datasheet to avoid substitution errors during purchasing.

Selection Notes

Select this component when an 8.2 V reference with ±5% tolerance is required in a DO-41 package. Verify that the 1.0 W power dissipation rating meets the thermal design constraints. Check that the specified operating temperature range of -65°C to +200°C satisfies the environmental conditions of the target application circuit.

Part Context

This component belongs to the 1N4728A through 1N4764A series of 1-watt silicon Zener diodes manufactured by Central Semiconductor Corp. The series utilizes a glass body construction within the standard DO-41 case outline. These devices are engineered specifically for robust voltage regulation tasks across various electronic systems.
