1N5339C/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5339C/TR12 is a silicon Zener diode with a nominal voltage of 5.6 V and a tolerance of ±2%. It features a maximum power dissipation of 5.0 watts at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes a T-18 axial leaded plastic package and includes a TR suffix indicating tape and reel packaging per EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

Single Zener Diodes Applications

• Voltage regulation circuits
• Surge protection applications
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The TR suffix indicates tape and reel configuration. Confirm RoHS compliance status as the base series may contain non-compliant variants. Ensure the component meets environmental requirements for the intended deployment environment before procurement.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V reference with tight ±2% tolerance is required. Consider the 5-watt power rating and thermal resistance characteristics for heat sinking needs. Verify that the axial lead form factor fits the mechanical constraints of the target printed circuit board layout.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333-5388B series of 5.0 watt Zener diodes. The series offers voltages from 3.3 to 200 volts with various tolerance options identified by suffix letters. The C suffix specifically denotes the tighter ±2% tolerance variant within this family.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5.6V 5W Zener diodes in the T-18 package. Verify electrical parameters such as dynamic impedance and reverse leakage current match the original specifications before substitution.
