1N4751A TR PBFREE

Overview

The Central Semiconductor Corp 1N4751A 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 30 V with a ±5% tolerance. The device operates within a temperature range of -65 °C to +200 °C and dissipates up to 1.0 W at 50 °C. Key electrical characteristics include a maximum reverse current of 5.0 μA at 22.8 V, a maximum Zener impedance of 40 Ω at the test current of 8.5 mA, and a forward voltage of 1.2 V maximum at 200 mA.

Feature Summary

• Provides reliable voltage regulation across a wide operating temperature range suitable for demanding environments.
• Utilizes a glass-encapsulated DO-41 axial leaded package for robust mechanical stability.
• Features low leakage current and defined dynamic impedance for stable circuit performance.

Applications

• Industrial equipment power supplies
• Commercial electronic systems
• Entertainment system control circuits
• Computer peripheral voltage regulation

Procurement Notes

Verify that the ordering suffix 'TR PBFREE' corresponds to the specific reel packaging and lead-free plating requirements mandated by your assembly process. Confirm compliance with RoHS directives and ensure the component meets environmental regulations applicable to your target market before finalizing procurement specifications.

Selection Notes

Select this component when a 30 V reference is required in an axial through-hole configuration. Ensure the application can accommodate the specified 1.0 W power dissipation limit and verify that the ±5% voltage tolerance aligns with the circuit's precision requirements. Consider the thermal management needs associated with the DO-41 package geometry.

Part Context

This part belongs to the 1N4728A through 1N4764A series of 1.0 Watt silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 3.3 V to 100 V, all maintaining a consistent 5% tolerance standard. These devices are engineered for general-purpose voltage regulation tasks requiring high reliability in standard axial packages.
