1N5241B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5241B/TR is a 0.5-watt glass axial-lead Zener diode housed in a DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 11 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates at a test current of 20 mA and features a maximum reverse leakage current of 2 µA at 8.4 V. Its electrical characteristics include a Zener impedance of 9.5 Ohms at 0.25 mA and a temperature coefficient of +0.076 %/°C. The component supports an operating temperature range from -65°C to +175°C and is supplied in tape and reel packaging.

Single Zener Diodes Feature Summary

• Overvoltage protection
• Current limiting applications

Single Zener Diodes Procurement Notes

Verify that the part number includes the TR suffix to confirm tape and reel packaging. Ensure the B suffix is present to guarantee the required ±5% voltage tolerance. Confirm RoHS compliance via the e3 suffix if restricted substances are prohibited. Cross-reference the manufacturer's datasheet for specific screening levels or military prefixes if environmental ruggedness is required.

Single Zener Diodes Selection Notes

Select this component when a precise 11 V reference is needed within a standard axial-lead form factor. The 500 mW power rating allows for moderate current handling without excessive heat dissipation. Consider the positive temperature coefficient for thermal stability requirements. Verify that the DO-35 package dimensions fit the target PCB layout constraints.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5-watt Zener voltage regulators. The series offers a wide selection of voltages from 2.4 to 200 volts. These components are JEDEC registered and utilize a hermetically sealed glass axial-lead construction. The series is designed for general-purpose voltage regulation tasks in commercial and industrial electronics.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N5241B devices meeting the same JEDEC specifications. Surface mount equivalents are available as MLL5241B in the DO-213AA MELF package. Internal bond options exist with the -1 suffix.
