1N5363AE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5363AE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, housed in a T-18 axial-lead plastic package. It provides a nominal Zener voltage of 30 V with a standard tolerance of ±10%, indicated by the 'A' 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, it is designed for high maximum DC currents when adequately heat sunk.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Withstands high surge stresses and exhibits minimal changes of voltage versus current
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against overvoltage conditions
• Reference voltage generation in industrial electronic systems

Single Zener Diodes Procurement Notes

Verify that the part number includes the 'e3' suffix to confirm RoHS compliance and the 'TR8' or similar designation to ensure the correct tape and reel packaging configuration. Confirm the 'A' suffix corresponds to the required ±10% voltage tolerance for your specific circuit design requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and a 30 V nominal breakdown voltage are required. Ensure adequate heat sinking is provided to handle high maximum DC currents, as the device relies on low thermal resistance design for optimal operation. Verify that the ±10% tolerance aligns with the precision needs of the application.

Single Zener Diodes Part Context

This component belongs to the Microsemi 1N5333B thru 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages ranging from 3.3 V to 200 V. Different tolerance levels are identified by specific suffix letters, such as 'B' for ±5% and 'A' for ±10%. The series is JEDEC registered and available in various military equivalent screening levels.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5W Zener diodes with a 30V nominal voltage and ±10% tolerance in a T-18 package. Surface mount equivalents in the SMBJ5333 to SMBJ5388B series may be considered if footprint adaptation is possible.
