1N5345AE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1N5345AE3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 9.1 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features an axial lead T-18 package. Electrical characteristics include a maximum dynamic impedance of 2.0 Ω at a test current of 150 mA, a maximum reverse leakage current of 7.5 μA at 6.25 V, and a maximum regulator current of 6.6 A.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for secure installation
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation circuits
• Surge protection applications
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'e3' suffix indicates RoHS compliance, while 'TR13' specifies tape and reel packaging per EIA-296 standards. Confirm the 'A' suffix corresponds to the necessary ±10% 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 is required for voltage regulation tasks. The 9.1 V nominal voltage and ±10% tolerance suit general-purpose applications. Consider the T-18 axial package for through-hole mounting. Verify thermal management capabilities, as steady-state power dissipation depends on adequate heat sinking or PCB copper pad dimensions.
