1N5361BE3/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5361BE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation between 3.3V and 200V. It features a nominal Zener voltage of 27V with a ±5% tolerance (B suffix) and operates within a temperature range of -65°C to +150°C. The device utilizes a T-18 axial lead package and includes an e3 suffix indicating RoHS compliance. Electrical characteristics include a maximum dynamic impedance of 5.0 ohms at a test current of 50 mA, a maximum reverse leakage current of 0.5 µA, and a maximum surge current capability of 120 A.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Moisture classification Level 1 requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage sources in measurement equipment

Single Zener Diodes Procurement Notes

Verify that the ordering suffix TR8 corresponds to the Tape & Reel packaging option as specified in the datasheet. Confirm the presence of the e3 suffix to ensure RoHS compliant annealed matte-Tin plating on the terminals. Ensure the B suffix is present to verify the standard ±5% voltage tolerance. Cross-reference the part number against the manufacturer's discontinuance notifications to confirm availability status.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating is required for high-current regulation tasks. The T-18 package provides low thermal resistance for effective heat sinking. Consider the specific Zener voltage and tolerance requirements; the B suffix indicates standard tolerance, while C or D suffixes offer tighter specifications if needed. Verify that the operating environment does not exceed the maximum junction temperature limits defined in the thermal characteristics.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series covers a wide voltage range from 3.3V to 200V in a standardized axial-leaded plastic encapsulated format. These devices are JEDEC registered and designed for robust performance in industrial and commercial applications requiring reliable voltage regulation.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series. Military screening options exist with JAN, JANTX, or JANTXV prefixes for enhanced reliability requirements.
