1N4760CPE3/TR12

Overview

The Microchip Technology 1N4760CPE3/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP to 1N4764AP series, manufactured by Microsemi's Scottsdale Division. It provides voltage regulation with a nominal Zener voltage of 68V and a tight tolerance of +/- 2%, indicated by the 'C' suffix. The device operates within an ambient temperature range of -65°C to +150°C and features a plastic encapsulated DO-41 (DO-204AL) package. Electrical characteristics include a maximum dynamic impedance of 150 Ohms at a test current of 3.7 mA, a maximum reverse current of 5 µA, and a maximum regulator current of 65 mA.

Feature Summary

• Provides precise voltage regulation with a standard 2% tolerance on nominal Zener voltage.
• Features a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards.
• Offers flexible axial-lead mounting terminals suitable for through-hole applications.
• Compliant with RoHS directives and classified as Level 1 moisture sensitivity.

Applications

• Voltage regulation circuits requiring stable reference voltages.
• Power supply protection against overvoltage conditions.
• Clamping applications for transient voltage suppression.

Procurement Notes

Verify that the specific ordering suffix matches the required electrical tolerances and packaging format. Confirm the manufacturer origin, as this component originates from the Microsemi Scottsdale Division. Ensure compliance with environmental directives such as RoHS is documented for your specific manufacturing requirements. Check for any military screening prefixes if higher reliability levels are necessary for the intended deployment environment.

Selection Notes

Select this component when a 68V regulation point with high precision is required. The 1W power dissipation rating supports moderate current loads compared to lower-power alternatives. The plastic construction offers lower thermal resistance than glass-body options. Consider the axial lead configuration for standard PCB layouts where surface mount equivalents like MLL4760A are not preferred.

Part Context

This part belongs to the extensive 1N4728A through 1N4764A series of silicon Zener diodes. The series covers a wide voltage selection from 3.3V to 100V. The 'P' suffix designates the plastic JEDEC package option, while the 'e3' suffix indicates RoHS compliance. This specific variant combines the 68V rating with the tighter 2% tolerance associated with the 'C' designation.

Replacement Considerations

Surface mount equivalents are available as MLL4760A or SMAJ4760A. For glass-body replacements, consult the separate datasheet for the G-suffix variants. Verify that substitute parts match the 1W power dissipation and 68V nominal voltage specifications.
