1N4760CE3/TR13

Overview

The Microchip Technology 1N4760CE3/TR13 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 (DO-204AL) axial-lead package. It provides voltage regulation with a nominal Zener voltage of 68 V and a tight tolerance of ±2%, indicated by the 'C' suffix. The device features RoHS-compliant annealed matte-tin plating ('e3') and tape-and-reel packaging ('TR'). Maximum ratings include a power dissipation of 1.0 W at 25°C, an operating temperature range of -65°C to +150°C, and a maximum reverse current of 13 µA at a test voltage of 51.7 V.

Feature Summary

• Provides precise voltage regulation with a standard ±2% tolerance on nominal Zener voltage.
• Utilizes void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards.
• Features flexible axial-lead mounting terminals suitable for standard through-hole applications.
• Includes RoHS-compliant annealed matte-tin plating solderable per MIL-STD-750 method 2026.

Applications

• Voltage regulation in electronic circuits over a broad operating current and temperature range.
• Reference voltage sources requiring stable DC output levels.
• Protection against voltage spikes in low-power signal processing systems.

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'C' for ±2% tolerance, 'e3' for RoHS compliance, and 'TR' for tape-and-reel packaging. Confirm the manufacturer designation as Microchip Technology or its predecessor entity Microsemi. Ensure the component meets the JEDEC registration standards for the 1N4760A type number. Check for any specific military screening prefixes if higher reliability levels are required for the application environment.

Selection Notes

Select this component when a 68 V reference with high precision is needed in an axial-lead package. The ±2% tolerance distinguishes it from standard 5% or 10% variants. Consider the 1.0 W power dissipation limit and thermal resistance characteristics for heat management. The plastic construction offers lower thermal resistance compared to glass-body options. Verify compatibility with the intended PCB layout for DO-41 footprint requirements.

Part Context

This part belongs to the popular 1N4728AP through 1N4764AP series of 1.0-watt Zener diodes. The series covers a voltage selection from 3.3 to 100 volts. The 1N4760 variant specifically targets the 68 V regulation point within this extensive lineup. These devices are JEDEC registered and widely used for general-purpose voltage regulation tasks in industrial and commercial electronics.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4760A equivalents with matching 68 V Zener voltage and ±2% tolerance. Ensure replacement parts maintain the DO-41 axial package and 1.0 W power rating. Verify that alternative sourcing maintains RoHS compliance and similar electrical characteristics such as dynamic impedance and reverse leakage current.
