1N5369A/TR8

Overview

The Microchip Technology 1N5369A/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation in axial-leaded T-18 packages. It features a nominal Zener voltage of 51 volts with a ±10% tolerance and operates within a temperature range of -65°C to +150°C. The device provides flexible mounting terminals and withstands high surge stresses while maintaining minimal voltage changes versus current.

Feature Summary

• Regulates voltage over a broad operating current and temperature range
• Flexible axial-lead mounting terminals
• Non-sensitive to ESD per MIL-STD-750 Method 1020
• Withstands high surge stresses

Applications

• Voltage regulation circuits requiring 51V reference
• High power dissipation applications with adequate heat sinking
• Surge stress environments

Procurement Notes

Verify component authenticity through authorized Microchip channels. Confirm RoHS compliance status as standard versions may not be compliant. Check datasheet for specific screening levels if military equivalents are required. Ensure proper handling procedures are followed during assembly.

Selection Notes

Select this component for applications needing precise 51V regulation with ±10% tolerance. Consider thermal management requirements due to 5W power dissipation capability. Verify package compatibility with existing PCB layouts using T-18 dimensions. Evaluate surge current ratings against expected transient conditions.

Part Context

Part of the 1N5333-5388B series offering voltages from 3.3V to 200V. Available in various tolerances identified by suffix letters. Surface mount equivalents exist as SMBJ/SMBG series. Military screening options available with MQ/MX/MV prefixes. Moisture classification Level 1 requires no dry pack.

Replacement Considerations

Equivalent parts include 1N5369B (±5% tolerance) or 1N5369C (±2% tolerance). Verify electrical parameters match application requirements when substituting different tolerance variants.
