1N5337CE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5337CE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series, housed in a T-18 axial-lead plastic package. It provides voltage regulation with a nominal Zener voltage of 4.7 V and a tight tolerance of ±2%, indicated by the C suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance via the e3 suffix. Packaged in tape and reel format per EIA-296 standards (TR suffix), it offers low thermal resistance for high DC current operation with adequate heat sinking.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation circuits requiring precise tolerance
• Power supply reference designs
• Protection against overvoltage conditions

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffixes match the required specifications: 'C' indicates a ±2% voltage tolerance, 'e3' confirms RoHS compliance, and 'TR12' denotes the tape and reel packaging format. Confirm the manufacturer designation as Microsemi Corporation or its successor entity. Ensure the component meets the necessary environmental and electrical requirements for the intended application before procurement.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V Zener voltage with ±2% tolerance is required in a 5-watt power dissipation class. The T-18 package supports high maximum DC currents provided adequate heat sinking is implemented. Consider the thermal resistance characteristics and derating curves for ambient temperature conditions above 25°C to ensure reliable operation within the specified junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 V to 200 V with various tolerance options identified by suffix letters. These devices are designed for robust performance in demanding environments, offering low thermal resistance and high surge current capabilities compared to lower-power alternatives.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 4.7 V Zener voltage, ±2% tolerance, 5 W power rating, and T-18 package. Verify compatibility with RoHS requirements if applicable. Other parts in the 1N5333-1N5388 series may be considered if voltage and tolerance specifications align.
