1N5345E3/TR13

Single Zener Diodes Overview

The Microchip Technology 1N5345E3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 8.7V with a ±5% tolerance, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18-2 axial lead package. The 'e3' suffix denotes RoHS compliance, while the 'TR13' suffix indicates tape and reel packaging per EIA-296 standards.

Single Zener Diodes 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
• Constructed with a void-free transfer molded thermosetting epoxy body

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Reference voltage sources for electronic systems
• Overvoltage protection components

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications: 'e3' confirms RoHS compliance, and 'TR13' specifies tape and reel packaging. Confirm the 'B' suffix corresponds to the necessary ±5% voltage tolerance. Ensure the component meets the specific thermal and electrical requirements for the intended application before procurement.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating and an 8.7V Zener voltage are required. Consider the T-18-2 axial lead package for through-hole mounting. Evaluate the thermal resistance characteristics and derating curves if operation at elevated temperatures or reduced heat sinking conditions is anticipated.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. These devices are designed for applications requiring robust voltage regulation and high surge current handling capabilities.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N5345 variants with different tolerances (e.g., 1N5345A for ±10%, 1N5345C for ±2%) or non-suffix versions for ±20%. Surface mount equivalents such as SMBJ5345B or SMBG5345B may be considered if footprint changes are acceptable.
