1N5335BE3

Single Zener Diodes Overview

The Microsemi Corporation 1N5335BE3 is a silicon unidirectional Zener diode with a nominal voltage of 3.9 V and a maximum power dissipation of 5 W at 25°C. It features a ±5% tolerance, a test current of 320 mA, and a maximum dynamic impedance of 2.0 Ω. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial leaded plastic package.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for versatile installation
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Surge protection applications
• High DC current operation with adequate heat sinking

Single Zener Diodes Procurement Notes

Verify the component against official Microsemi datasheets to confirm specifications such as voltage tolerance and thermal resistance. Ensure the ordering suffix matches the required RoHS compliance and packaging format. Cross-reference part numbers carefully as distributors may list obsolete or inactive status for this specific model.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V reference with 5 W power handling is required. Consider the T-18 package dimensions and thermal characteristics for PCB layout. Verify that the application environment stays within the specified -65°C to +150°C operating range and accounts for derating curves if ambient temperatures exceed 25°C.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 'e3' suffix indicates RoHS compliance, while the 'B' suffix denotes a standard ±5% voltage tolerance.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B series. Other voltage options within the same 5 W series include 1N5334BE3 (3.6 V) and 1N5336BE3 (4.3 V).

Single Zener Diodes FAQ

What is the maximum reverse leakage current for the 1N5335BE3?

The maximum reverse leakage current is 50 µA when tested at 1.0 V.

How is polarity indicated on the 1N5335BE3?

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.
