1N4763CPE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N4763CPE3/TR12 is a silicon Zener diode with a nominal voltage of 91 V and a 2% tolerance. It operates in the DO-41 axial package, dissipating up to 1.0 W at 25°C. The device features a maximum reverse current of 5 µA at 76.0 V and a dynamic impedance of 250 Ω at a test current of 2.8 mA. It withstands surge currents up to 3000 mA and functions within a temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with tight 2% tolerance for stable reference applications
• Features flexible axial-lead mounting terminals compatible with standard through-hole processes
• Constructed with void-free transfer molded thermosetting epoxy meeting UL94V-0 standards
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring high precision
• Overvoltage protection systems
• Reference voltage sources in electronic equipment

Single Zener Diodes Procurement Notes

Verify that the part number includes the C suffix for 2% tolerance and the e3 suffix for RoHS compliance. Confirm the TR12 designation indicates tape and reel packaging. Ensure the component matches the specified JEDEC type 1N4763A electrical characteristics and physical dimensions.

Single Zener Diodes Selection Notes

Select this component when a 91 V Zener voltage with strict 2% tolerance is required. The plastic construction offers lower thermal resistance compared to glass-body options. Verify that the 1.0 W power dissipation rating and 250 Ω dynamic impedance meet the specific circuit requirements.

Single Zener Diodes Part Context

This component belongs to the 1N4728AP thru 1N4764AP series of 1.0 watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series provides extensive voltage selection from 3.3 to 100 volts. The 'P' suffix denotes plastic encapsulation, while the 'e3' suffix indicates RoHS compliant annealed matte-Tin plating.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N4763A variants with matching 91 V and 2% tolerance specifications. Surface mount equivalents such as SMAJ4763A are available if board space constraints require a different form factor.
