1N5334B/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5334B/TR12 is a silicon unidirectional Zener diode with a nominal voltage of 3.6 V and a maximum power dissipation of 5 W at 25°C. It features a ±5% tolerance, a test current of 350 mA, and a maximum dynamic impedance of 2.5 Ω. The device operates within a temperature range of -65°C to +150°C and has a maximum reverse leakage current of 150 µA at 1.0 V. Packaged in an axial T-18 case with tape and reel delivery, it provides stable voltage regulation for electronic circuits.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official Microsemi documentation to confirm package type and screening level. Confirm RoHS compliance status if required by your assembly process. Check component availability as this part number may be subject to discontinuation or lifecycle changes. Ensure the tape and reel packaging matches your automated placement equipment specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V regulation point is required with a 5 W power handling capacity. The T-18 axial package is appropriate for designs needing robust mechanical stability and heat sinking capabilities. Consider the thermal resistance characteristics and derating curves for high-current applications. Verify that the ±5% tolerance meets the circuit's precision requirements compared to tighter tolerance alternatives.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a broad selection of voltages ranging from 3.3 V to 200 V. The 'B' suffix indicates a standard ±5% voltage tolerance. The '/TR12' suffix denotes the tape and reel packaging format for automated manufacturing processes.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5 W Zener diodes with a 3.6 V nominal voltage and similar axial T-18 packaging. Verify pinout compatibility and thermal performance characteristics before substitution. Cross-reference with Microsemi's current product portfolio for updated equivalents.
