1N5369CE3/TR8

Overview

The Microchip Technology 1N5369CE3/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 51V 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. The component is RoHS compliant, as denoted by the 'e3' suffix, and is supplied in tape and reel packaging.

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
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation in electronic instrumentation

Procurement Notes

Verify the specific suffixes on the part number to confirm exact electrical tolerances and compliance status. The 'C' suffix indicates a ±2% voltage tolerance, while the 'e3' suffix confirms RoHS compliance. Ensure the ordering suffix matches the required packaging format, such as TR for tape and reel. Confirm that the manufacturer designation aligns with current corporate structures following industry acquisitions.

Selection Notes

Select this component when a precise 51V reference is required with tight manufacturing tolerances. The 5-watt power dissipation rating allows for operation at high DC currents provided adequate heat sinking is utilized. Consider the thermal resistance specifications and derating curves if the application involves elevated ambient temperatures or limited airflow conditions.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally developed by Microsemi. The series offers a wide selection of voltages ranging from 3.3V to 200V. These plastic encapsulated components are designed for robust performance in demanding environments, featuring low thermal resistance and moisture classification Level 1.

Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B series.
