1N5336/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5336/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series, housed in an axial-lead T-18 package with a TR suffix indicating tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 4.3 V with a standard ±5% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 2.0 ohms at a test current of 290 mA. It withstands high surge stresses and includes moisture classification Level 1.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals 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 in power supply circuits
• Protection against overvoltage conditions
• Reference voltage generation in electronic systems

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration to confirm the exact voltage tolerance and compliance status. Confirm that the TR suffix aligns with required tape and reel specifications for automated assembly processes. Ensure thermal management strategies account for the specified junction-to-lead thermal resistance when designing heat sinking solutions.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 4.3 V reference with moderate precision. Consider the 5-watt power dissipation capability and low thermal resistance design for high-current operations. Evaluate the need for tape and reel packaging if integrating into surface mount or automated insertion lines.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. These plastic encapsulated devices are designed for robust performance in demanding environments.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5-watt Zener diodes with a 4.3 V rating and similar axial leaded packages. Verify compatibility regarding thermal resistance, surge current ratings, and voltage tolerance before substitution.
