1N5337AE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5337AE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, housed in an axial-lead T-18 package with tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 4.7 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 2.0 ohms at a test current of 260 mA. It includes RoHS compliance via the e3 suffix and meets Level 1 moisture classification standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for through-hole integration
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications: 'A' indicates ±10% voltage tolerance, 'e3' confirms RoHS compliance, and 'TR12' specifies tape and reel packaging. Confirm the manufacturer designation as Microsemi Corporation or its successor entity. Ensure the component meets the specified thermal resistance and power dissipation requirements for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V regulated output is required with moderate precision. The ±10% tolerance suits general-purpose applications where tighter tolerances are unnecessary. Consider the 5 W power rating and low thermal resistance design for high-current operations requiring adequate heat sinking. Verify compatibility with existing PCB layouts due to the specific T-18 axial lead dimensions.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi Corporation's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V. These plastic encapsulated devices are designed for robust performance in demanding environments, featuring void-free transfer molded epoxy bodies meeting UL94V-0 flammability ratings.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5337B or SMBG5337B are available within the same product family. For direct replacements, verify that any substitute maintains the 4.7 V Zener voltage, 5 W power dissipation, and T-18 package form factor.
