1N5369C/TR8

Overview

The Microchip Technology 1N5369C/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by Microsemi. It provides voltage regulation at a nominal Zener voltage of 51 V with 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 a T-18 axial-lead package. Electrical characteristics include a maximum dynamic impedance of 27 Ohms and a maximum reverse current of 0.5 µA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals 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

Applications

• Voltage regulation circuits requiring high power dissipation
• Power supply protection against overvoltage conditions
• Reference voltage generation in industrial equipment

Procurement Notes

Verify component authenticity and datasheet alignment when sourcing this part. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration. Ensure compliance with applicable environmental regulations relevant to the intended deployment region. Review manufacturer documentation for any updates regarding product discontinuance or manufacturing changes prior to procurement.

Selection Notes

Select this component for applications demanding precise voltage regulation with a ±2% tolerance. The 5-watt power rating supports high DC currents when adequate heat sinking is provided. Verify that the T-18 package dimensions fit the design constraints. Consider thermal resistance specifications for proper PCB layout and heat dissipation strategies.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon Zener diodes originally developed by Microsemi. The series offers a wide selection of voltages from 3.3 V to 200 V. The 'TR8' suffix indicates tape and reel packaging options available for automated assembly processes.

Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. Other manufacturers may offer compatible parts within the same voltage and power ratings, but verify pinout and electrical parameters carefully.
