1N5265B/TR

Single Zener Diodes Overview

The 1N5265B/TR is a 0.5-watt glass axial-lead Zener diode manufactured by Microsemi (Microchip Technology). It provides a nominal Zener voltage of 62 V with a standard tolerance of ±5%, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse current of 100 µA at 47 V. Its electrical characteristics include a test current of 2.0 mA, a maximum Zener impedance of 185 Ohms at 0.25 mA, and a voltage temperature coefficient of +0.097 %/°C.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required package and screening level. Confirm RoHS compliance status if applicable. Ensure the manufacturer designation aligns with project requirements, as production may originate from Microsemi or Microchip Technology divisions. Cross-reference datasheet specifications against specific design constraints before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 62 V Zener voltage with ±5% tolerance is required in a DO-35 axial package. Consider the 0.5 W power dissipation limit and derating curves for thermal management. Verify that the +0.097 %/°C temperature coefficient meets circuit stability requirements. Ensure the operating environment falls within the specified -65°C to +175°C range.

Single Zener Diodes Part Context

This part 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 V to 200 V in standard 5% or 10% tolerances. These devices are JEDEC registered and utilize a hermetically sealed glass DO-35 package. The 'TR' suffix indicates tape and reel packaging options available for automated assembly.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF style package. Other tolerance levels can be identified by different suffix letters such as C or D for tighter tolerances.
