1N4763UR-1/TR

Overview

The Microchip Technology 1N4763UR-1/TR is a surface mountable 1.0 W glass Zener diode in the DO-213AB MELF package. It provides a nominal Zener voltage of 91 V with a standard tolerance of +/- 5%. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse current of 5 µA at 76.0 V. Electrical characteristics include a test current of 2.8 mA, dynamic impedance of 250 Ohms, and steady-state power dissipation of 1.00 watts.

Feature Summary

Hermetically sealed glass construction suitable for high reliability applications
Surface mount design ideal for high density mounting requirements
Inherently radiation hard per MicroNote 050

Applications

Voltage regulation in high density electronic circuits
High reliability systems requiring source control drawings
Applications necessitating low parasitic performance

Procurement Notes

Verify the specific suffix configuration against the manufacturer's datasheet to confirm electrical tolerances and screening levels. Ensure the ordering part number matches the required voltage tolerance and RoHS compliance status. Confirm that the tape and reel packaging specifications align with automated assembly equipment requirements before finalizing procurement orders.

Selection Notes

Select this component when a 1-watt surface mount Zener diode with hermetic sealing is required. The DO-213AB package offers a leadless form factor beneficial for space-constrained designs. Consider the wide operating temperature range and radiation hardness for demanding environmental conditions or specialized industrial applications.

Part Context

This device belongs to the 1N4728UR through 1N4764AUR series of surface mount glass Zener diodes manufactured by Microsemi (now Microchip Technology). The series serves as the surface mount equivalent to the JEDEC registered 1N4728A through 1N4764A axial leaded series, maintaining identical electrical performance while utilizing the DO-213AB outline.
