1N5341E3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5341E3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 6.2 V with a standard tolerance of ±5%. The device features a T-18 axial lead package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 1.0 Ohms and a maximum reverse current of 1 µA. The component is RoHS compliant and available in tape and reel packaging.

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 for through-hole applications
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Power supply reference designs
• Protection against overvoltage conditions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR12' against official documentation to confirm tape and reel specifications, as datasheets indicate 'TR' for tape and reel options. Confirm RoHS compliance status via the 'e3' suffix designation. Check for discontinuance notifications or lifecycle status updates from Microchip Technology, as this product line may have been subject to manufacturing transitions.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V Zener voltage with ±5% tolerance is required for 5-watt applications. Ensure the design accommodates the thermal resistance of 25 °C/W junction to lead. Verify that the circuit can handle the specified maximum regulator current and surge current ratings. Consider the T-18 package dimensions for PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally produced by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 V to 200 V. The 'e3' suffix indicates RoHS compliance, while the 'TR' suffix denotes tape and reel packaging. Microchip Technology now manages these products following its acquisition of Microsemi.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5341B (standard bulk) or 1N5341BE3 (RoHS compliant bulk). Surface mount equivalents are available as SMBJ5341 or SMBG5341. Verify that any substitute matches the 6.2 V Zener voltage, 5 W power rating, and T-18 package form factor.
