1N5341B/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5341B/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 6.2 V and ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse leakage current of 1 µA at 3.0 V and a dynamic impedance of 1.0 Ω. The device supports a maximum regulator current of 765 mA and withstands surge currents up to 12.4 A. Packaged in the T-18 axial lead format, it utilizes void-free transfer molded epoxy meeting UL94V-0 standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage changes versus current
• Features flexible axial-lead mounting terminals for through-hole integration
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5W power dissipation
• High surge stress environments
• General purpose electronic equipment utilizing axial leads

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the 1N5341B series was originally JEDEC registered by Microsemi and later acquired by Microchip. Confirm RoHS compliance status, as standard suffixes may differ from e3 variants. Ensure the TR12 tape and reel packaging matches the required EIA-296 specifications for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V reference with ±5% accuracy is required. The T-18 package offers low thermal resistance for heat sinking applications. Verify that the 1.0 Ω dynamic impedance meets circuit sensitivity requirements. Consider the 765 mA maximum current limit against peak load demands.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The 'B' suffix indicates a standard ±5% voltage tolerance. The 'TR' suffix denotes availability in tape and reel packaging, while the '12' typically specifies reel dimensions or quantity per industry standards.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5341B equivalents. Cross-reference electrical parameters such as 6.2 V Zener voltage, 5 W power rating, and T-18 package dimensions to ensure mechanical and functional compatibility.
