1N5242B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5242B/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 (DO-204AH) package, featuring a nominal voltage of 12 V with ±5% tolerance. It operates within a temperature range of -65°C to +175°C and includes a tape-and-reel option indicated by the TR suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Includes internal bonds available with the -1 suffix option

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

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 status if applicable to your manufacturing requirements.

Single Zener Diodes Selection Notes

Select this component when a standard 12 V reference is needed in a DO-35 package. The B suffix ensures tighter voltage tolerances compared to the A suffix. Consider the TR suffix for automated assembly processes requiring reel packaging.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 to 200 V in standard 5% or 10% tolerances, housed in hermetically sealed glass axial-lead packages.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as MLL5242B in the DO-213AA MELF style package. Other manufacturers may offer compatible parts within the same JEDEC registered numbering system.
