1N5351E3/TR13

Overview

The Microchip Technology 1N5351E3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 14V with a ±5% tolerance (indicated by the 'B' suffix). The device features an axial-lead T-18 plastic package and operates within a temperature range of -65°C to +150°C. The 'e3' suffix denotes RoHS compliance, while the 'TR13' suffix indicates tape and reel packaging per EIA-296 standards.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

Applications

• Voltage regulation in power supply circuits
• Reference voltage generation in electronic systems
• Circuit protection against overvoltage conditions

Procurement Notes

Verify that the part number includes the correct suffixes: 'B' for ±5% tolerance, 'e3' for lead-free/RoHS compliance, and 'TR13' for tape and reel packaging. Confirm the manufacturer origin as Microsemi or its successor entity Microchip Technology. Ensure the component matches the specified T-18 axial-lead package dimensions and void-free transfer molded epoxy body characteristics.

Selection Notes

Select this component when a 14V regulation point is required with moderate precision. The 5W power dissipation rating allows operation at high DC currents provided adequate heat sinking is utilized. Consider the thermal resistance specifications for both lead-mounted and PCB-mounted configurations to ensure safe operating temperatures under load.

Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages ranging from 3.3V to 200V. Different tolerance levels are available via specific suffix letters, such as A for ±10%, C for ±2%, and D for ±1%. Military equivalent screening options exist with MQ, MX, or MV prefixes.

Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series. For direct replacement, verify that any substitute maintains the 14V Zener voltage, 5W power rating, and compatible axial-lead or surface-mount form factor.
