1N5239BE3/TR

Single Zener Diodes Overview

The Microchip Technology 1N5239BE3/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 9.1 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse leakage current of 3 µA at 7 V. Electrical characteristics include a Zener impedance of 10 Ω at a test current of 20 mA and a forward voltage of 1.5 V maximum at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features hermetically sealed glass axial-lead construction for durability
• Includes RoHS compliant plating options identified by the e3 suffix

Single Zener Diodes Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection stages in electronic systems
• Power supply output stabilization

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'e3' suffix indicates RoHS compliance, while 'TR' specifies tape and reel packaging. Confirm the 'B' suffix corresponds to the necessary ±5% voltage tolerance. Ensure the manufacturer designation aligns with project requirements, as production may originate from Microsemi or Microchip Technology divisions.

Single Zener Diodes Selection Notes

Select this component when a 9.1 V regulated voltage is required with tight tolerance limits. The DO-35 package suits through-hole mounting applications. Verify thermal derating requirements against the power dissipation curve if operating near maximum ratings. Consider the low capacitance characteristic for high-frequency signal integrity needs.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener diodes. The series offers a wide selection of voltages from 2.4 V to 200 V. The specific model utilizes standard JEDEC registration numbers for identification and compatibility within general-purpose electronic designs.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5239B and 1N5239B/TR from Microchip Technology. Other manufacturers producing 1N5239 variants may serve as substitutes if electrical parameters match exactly.
