1N5336A/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5336A/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation across a broad operating current and temperature range. It features a nominal Zener voltage of 4.3V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial-lead package. The TR12 suffix denotes tape and reel packaging compliant with EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation over a wide operating current and temperature range
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Constructed with a void-free transfer molded thermosetting epoxy body

Single Zener Diodes Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply reference designs utilizing axial-lead components
• Industrial equipment operating under high surge stress conditions

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the datasheet to ensure correct tolerance and packaging selection. Confirm that the 'TR12' designation aligns with the required tape and reel specifications for automated assembly processes. Cross-reference the part number with official Microsemi documentation to validate manufacturing status and availability constraints.

Single Zener Diodes Selection Notes

Select this component when a 4.3V regulation point with ±10% tolerance is required in a 5-watt power dissipation class. Ensure adequate heat sinking is provided to maintain operation within the specified thermal resistance limits. Consider the T-18 package dimensions for PCB layout compatibility and verify lead length requirements for soldering procedures.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of axial-leaded 5.0-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a voltage selection from 3.3 to 200 volts with various tolerance options identified by suffix letters. These plastic encapsulated devices are moisture classification Level 1 and support military equivalent screening levels via specific prefix identifiers.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available for the same voltage ratings.
