1N5351BE3/TR13

Overview

The Microchip Technology 1N5351BE3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 14V with a tight tolerance of ±2%, indicated by the 'C' suffix in the base part number (1N5351C). The device features an axial-lead T-18 package and operates within a temperature range of -65°C to +150°C. It is RoHS compliant, as denoted by the e3 suffix, and supplied in tape and reel packaging.

Feature Summary

• Provides precise voltage regulation with ±2% tolerance for stable reference applications
• Capable of handling high surge stresses and maximum DC currents with adequate heat sinking
• Features flexible axial-lead mounting terminals suitable for various board layouts
• Moisture classification Level 1 requiring no dry pack storage

Applications

• Voltage regulation circuits requiring high precision
• Power supply reference designs
• Protection against overvoltage conditions

Procurement Notes

Verify the specific suffix configuration when ordering. The 'TR13' indicates tape and reel packaging, while the 'e3' confirms lead-free compliance. Ensure the base part number matches the required voltage and tolerance specifications, as the datasheet lists distinct suffixes for different tolerances. Confirm availability and production timelines directly with the manufacturer or authorized distributors.

Selection Notes

Select this component for applications requiring a 14V Zener voltage with strict ±2% tolerance. Consider the 5W power dissipation rating and thermal resistance characteristics for heat management. Verify that the operating current and temperature range align with system requirements. Compare against other suffix options if different tolerance levels are acceptable.

Part Context

This component belongs to the Microsemi (now Microchip Technology) Scottsdale Division's 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. These devices are JEDEC registered and offer a wide selection of voltages from 3.3V to 200V. The series includes various tolerance options identified by suffix letters, such as B for ±5%, C for ±2%, and D for ±1%. The e3 suffix denotes RoHS compliance.

Replacement Considerations

Direct replacements must match the 14V Zener voltage, 5W power rating, and ±2% tolerance. Check for equivalent axial-lead packages like DO-201AH. Verify thermal characteristics and maximum current ratings. Note that the 1N5351CE3 variant shares the same electrical profile but may differ in packaging quantity.
