1N5337AE3/TR13

Single Zener Diodes Overview

The Microsemi Corporation 1N5337AE3/TR13 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333-5388B series, featuring an axial lead T-18 package and RoHS compliance. It provides a nominal voltage of 4.7V with ±10% tolerance (A suffix). Key electrical parameters include a maximum dynamic impedance of 2.0 ohms at a test current of 260 mA, a maximum reverse leakage current of 5 µA at 1.0 V, and a maximum regulator current of 1010 mA. The device withstands a surge current of 450 A and operates within a temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and features minimal changes of voltage versus current
• Flexible axial-lead mounting terminals for secure installation
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation circuits
• Surge protection applications
• High reliability 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 indicates the required ±10% voltage tolerance. Ensure the component matches the specified T-18 axial lead package dimensions and thermal characteristics before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and 4.7V nominal voltage are required. The ±10% tolerance suits general-purpose regulation needs. Consider the low thermal resistance design for high DC current operation with adequate heat sinking. Verify compatibility with MIL-PRF-19500 screening requirements if military equivalent levels are necessary.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V. Surface mount equivalents are available in SMBJ and SMBG packages. The product line supports various tolerance options and military screening prefixes.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5337 or SMBG5337 may be considered for footprint adaptation. For higher reliability requirements, screened versions with MQ, MX, or MV prefixes are available. Direct replacements must match the 5W power rating and 4.7V specification.
