1N4760UR-1/TR

Overview

The Microchip Technology 1N4760UR-1/TR is a surface mount glass Zener diode in the DO-213AB MELF package. It provides a nominal Zener voltage of 68 V with a standard tolerance of ±5%. The device operates at a test current of 3.7 mA and features a maximum dynamic impedance of 150 Ohms. It dissipates up to 1.0 watt of power within an operating temperature range of -65°C to +175°C.

Feature Summary

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

Applications

• Voltage regulation in high density circuit designs
• High reliability electronic systems requiring hermetic sealing
• Applications necessitating radiation hardness

Procurement Notes

Verify the specific ordering suffix against official documentation, as it dictates packaging and compliance details. Confirm that the component meets source control drawing requirements if high reliability screening is necessary. Ensure compatibility with JEDEC surface mount outlines during integration.

Selection Notes

Select this component when a 68 V regulation point is required in a surface mount configuration. Consider the low parasitic characteristics and wide thermal operating range. Verify that the 1.0 W power dissipation rating aligns with the thermal management capabilities of the target printed circuit board footprint.

Part Context

This part belongs to the 1N4728AUR through 1N4764AUR series of 1-watt glass Zener diodes. These devices are electrically equivalent to the axial-leaded 1N4728A through 1N4764A registration but utilize the DO-213AB outline. The series offers various tolerance options and screening levels for military and commercial use.

Replacement Considerations

Equivalent plastic body axial-leaded equivalents include the 1N4760A. Surface mount SMAJ equivalents are available as SMAJ4760A.
