Overview
The Microchip Technology 1N4747CPE3/TR8 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 20V and a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS-compliant annealed matte-tin plating, designated by the 'e3' suffix. It is supplied in tape and reel packaging, specified by the 'TR' suffix.
Feature Summary
- Provides precise voltage regulation with a tight ±2% tolerance on the nominal Zener voltage.
- Features a void-free transfer molded thermosetting epoxy body that meets UL94V-0 flammability standards.
- Offers flexible axial-lead mounting terminals suitable for standard through-hole applications.
- Includes RoHS-compliant annealed matte-tin plating on terminals for solderability.
Applications
- Voltage regulation circuits requiring stable reference voltages.
- Protection against overvoltage conditions in electronic systems.
- Clipping and clamping applications in signal processing.
Procurement Notes
Verify the specific ordering suffixes to confirm package type, tolerance, and environmental compliance. The 'P' suffix indicates plastic construction, while 'e3' confirms RoHS compliance. Ensure the 'TR' suffix matches the required tape and reel packaging format for automated assembly processes.
Selection Notes
Select this component when a 20V Zener voltage with high precision is required. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Consider the operating temperature range and power dissipation limits relative to the ambient conditions and board layout.
Part Context
This part belongs to the popular 1N4728A through 1N4764A series of 1.0-watt Zener diodes. The series provides a wide selection of voltages from 3.3 to 100 volts. The 'C' suffix denotes a tighter 2% tolerance compared to the standard 5% tolerance of the 'A' suffix variants.
Replacement Considerations
Equivalent parts include other 1N4747 variants with matching voltage and tolerance, such as 1N4747A or 1N4747AP, provided the package and tolerance requirements are met. Verify compatibility with existing circuit designs before substitution.
