1N5338CE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5338CE3/TR12 is a JEDEC registered silicon 5.0-watt Zener diode in the 1N5333-5388B series, housed in an axial-leaded T-18 package with a TR suffix for tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 5.1 V with a tight tolerance of ±2%, as 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.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and exhibits minimal changes of voltage versus current
• Features flexible axial-lead mounting terminals suitable for through-hole applications

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High specified maximum current applications when adequately heat sunk
• Circuits requiring non-sensitive ESD protection per MIL-STD-750 Method 1020

Single Zener Diodes Procurement Notes

Verify the specific electrical characteristics against the official datasheet before integration. Confirm that the RoHS compliant e3 suffix and tape and reel TR packaging align with manufacturing requirements. Ensure thermal management strategies account for the 5.0-watt power dissipation rating and junction-to-lead thermal resistance specifications during operation.

Single Zener Diodes Selection Notes

Select this component for applications requiring precise voltage regulation with a ±2% tolerance. The axial lead configuration supports flexible mounting, while the wide operating temperature range ensures reliability in demanding environments. Verify that the required surge current handling and dynamic impedance meet the circuit's transient response needs.

Single Zener Diodes Part Context

This part belongs to the 1N5333B thru 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi. The series offers a selection from 3.3 to 200 volts with various tolerances identified by suffix letters. These plastic encapsulated devices are designed for high maximum DC currents with adequate heat sinking due to their low thermal resistance design.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. Military screening levels can be obtained by adding MQ, MX, or MV prefixes to JAN, JANTX, and JANTXV variants respectively.
