1N5335E3/TR13

Single Zener Diodes Overview

The Microsemi Corporation 1N5335E3/TR13 is a silicon Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 3.9 V with a standard tolerance of ±5%. The device operates in an axial-lead T-18 package and dissipates up to 5.0 watts of power at 25°C. Electrical characteristics include a maximum dynamic impedance of 2.0 ohms, a test current of 320 mA, and a maximum reverse current of 50 µA. It withstands surge currents up to 1220 A and functions 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 exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile integration
• 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
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement equipment

Single Zener Diodes Procurement Notes

Verify that the ordering suffix TR13 corresponds to the tape and reel packaging option as specified by EIA-296 standards. Confirm RoHS compliance via the e3 suffix designation. Ensure the component matches the specific 3.9 V Zener voltage requirement and ±5% tolerance associated with the B suffix within the part number structure.

Single Zener Diodes Selection Notes

Select this component when a 5-watt axial-leaded Zener diode is required for applications needing robust thermal performance and high surge current handling. The T-18 plastic encapsulated body offers low thermal resistance. Consider the specific voltage tolerance requirements, as the B suffix indicates a standard ±5% tolerance suitable for general-purpose regulation tasks.

Single Zener Diodes Part Context
