1N5337CE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5337CE3/TR8 is a silicon Zener diode with a nominal voltage of 4.7V and a tolerance of ±2%. It features a maximum power dissipation of 5W at 25°C, operating temperatures from -65°C to +150°C, and a thermal resistance of 25°C/W junction-to-lead. The device utilizes a T-18 axial lead plastic package, RoHS compliant construction (e3 suffix), and tape-and-reel packaging (TR8 suffix).

Single Zener Diodes Feature Summary

• Provides precise voltage regulation within a tight ±2% tolerance.
• Capable of handling high surge stresses and steady-state currents with adequate heat sinking.
• Features flexible axial-lead mounting terminals for versatile integration.

Single Zener Diodes Applications

• Voltage regulation in broad operating current and temperature ranges.
• High-power protection circuits requiring robust surge withstand capability.
• Applications necessitating moisture classification Level 1 without dry pack requirements.

Single Zener Diodes Procurement Notes

Verify the specific suffixes against official documentation to confirm exact electrical tolerances, compliance status, and packaging format. Ensure the TR8 designation aligns with required reel specifications and that the e3 suffix confirms RoHS compliance for the intended manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a 4.7V reference with ±2% accuracy is required in a 5W axial package. Consider the thermal resistance and derating curves for high-current applications. Verify compatibility with MIL-PRF-19500 screening if military-grade reliability is mandated.

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 voltage selection from 3.3V to 200V with various tolerance options defined by suffix letters. The e3 suffix indicates RoHS compliance, while the TR8 suffix specifies tape-and-reel packaging.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 4.7V 5W Zener diodes with ±2% tolerance in T-18 packages. Cross-reference with Microsemi's SMBJ or SMBG surface mount equivalents if form factor changes are acceptable. Verify thermal and electrical parameters match before substitution.

Single Zener Diodes FAQ

What does the 'C' suffix indicate for this Zener diode?

The 'C' suffix designates a standard voltage tolerance of plus or minus 2%.

Is the 1N5337CE3/TR8 sensitive to electrostatic discharge?
