1N5334AE3/TR13

Single Zener Diodes Overview

The Microsemi Corporation 1N5334AE3/TR13 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333-5388B series, housed in an axial T-18 package with tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 3.6 V with a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 2.5 ohms at a test current of 350 mA. It withstands a maximum surge current of 500 A and exhibits a forward voltage of 1.2 V maximum at 1.0 A.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for secure installation
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Protection against voltage spikes and transients
• Reference voltage sources in electronic systems

Single Zener Diodes Procurement Notes

Verify that the part number includes the e3 suffix to confirm RoHS compliance and the TR13 suffix to ensure tape and reel packaging. Confirm the A suffix corresponds to the required ±10% voltage tolerance. Check for any prefix identifiers if military screening levels are needed. Ensure adequate heat sinking is planned for operation near maximum DC currents.

Single Zener Diodes Selection Notes

Select this component when a 5-watt axial Zener diode with a 3.6 V nominal rating is required. The ±10% tolerance suits applications where tighter precision is not critical. Consider the low thermal resistance design for high-current operations. Verify that the T-18 package dimensions fit the available board space and that the lead length meets soldering requirements.

Single Zener Diodes Part Context

This device belongs to the 1N5333 through 1N5388B series of 5.0-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 to 200 volts. These plastic encapsulated diodes are designed for robust performance in various industrial and commercial applications requiring reliable voltage regulation.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. Other parts in the same series may be used if different voltage ratings are acceptable. Verify that any substitute matches the 5-watt power dissipation and T-18 package constraints.

Single Zener Diodes FAQ

What does the 'A' suffix indicate for this part?

The 'A' suffix identifies the device as having a standard voltage tolerance of plus or minus 10%.

Is dry pack storage required for this component?

No, the device has a moisture classification of Level 1 per IPC/JEDEC J-STD-020B and does not require dry pack storage.

How is polarity indicated on the component?

Polarity is indicated by a band on the cathode end; the diode must be operated with the banded end positive with respect to the opposite end.
