1N5341A/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5341A/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation in axial-leaded through-hole applications. It features a nominal Zener voltage of 6.2 V with a ±10% tolerance and operates within a temperature range of -65°C to +150°C. The device utilizes a T-18 package and includes a TR suffix indicating tape and reel packaging per EIA-296 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 changes in voltage versus current
• Features flexible axial-lead mounting terminals suitable for standard PCB assembly

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5W power dissipation
• Power supply reference stages
• Overvoltage protection networks

Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status via the e3 suffix if required. Ensure the TR suffix matches the intended automated assembly process. Validate that the specific lot corresponds to the Microsemi/Microchip lineage as indicated in the documentation.

Single Zener Diodes Selection Notes

Select this component when a 6.2V regulation point is required with moderate tolerance. The 5W power rating allows operation at high DC currents provided adequate heat sinking is implemented. Consider the thermal resistance characteristics and derating curves for ambient temperature conditions above 25°C to ensure reliable performance.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. These devices are characterized by low thermal resistance and robust construction for industrial applications.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N5341 variants with matching electrical ratings. Cross-reference with 1N5341B for tighter ±5% tolerance requirements. Verify pinout compatibility and thermal management capabilities before substituting.
