1N5337E3/TR13

Single Zener Diodes Overview

The Microsemi Corporation 1N5337E3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 volts with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and utilizes an axial-lead T-18 package. Electrical characteristics 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.

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 suitable for through-hole integration
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation circuits
• Surge protection systems
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify that the component matches the specific part number 1N5337E3/TR13 to ensure correct voltage rating and tolerance. Confirm the presence of the e3 suffix indicates RoHS compliance and the TR suffix confirms tape and reel packaging. Cross-reference datasheet specifications against design requirements to validate thermal resistance and power dissipation limits under intended operating conditions.

Single Zener Diodes Selection Notes

Select this component when a 4.7-volt reference with ±5% tolerance is required in a 5-watt axial package. Ensure adequate heat sinking is provided to maintain operation within the specified thermal resistance limits. Consider the T-18 form factor for compatibility with existing through-hole board layouts and verify that the maximum surge current capability meets transient protection demands.

Single Zener Diodes Part Context
